| 20090041507 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS INCLUDING SAME - A developing device of the present invention has a toner supply opening in a first carrying path and in the upstream of the developer carrying direction of a first carrying screw which is further from a developing roller; and a moquette member having feathers on its surface, and being provided, along the developer carrying direction, on the first carrying path. With this arrangement, it is possible to realize a compact developing device having a simple arrangement in which the supplied toner is speedily mixed with the preexisted developer, and the stable toner which is uniformly dispersed and charged can be speedily supplied for development. | 02-12-2009 |
| 20090202276 | TONER REPLENISHING APPARATUS AND IMAGE FORMING APPARATUS - A toner replenishing apparatus capable of, without increasing a drive torque for rotating the toner replenishing container, scraping toner adhered in a toner replenishing container to reduce the quantity of residual toner that remains unfed from the toner replenishing container, is provided. The toner replenishing apparatus includes a toner replenishing container for replenishing toner stored therein to a developing section by rotation of the toner replenishing container, a magnetic body movably provided in the toner replenishing container, and a magnet disposed closely to an outer peripheral surface of the toner replenishing container and attracting the magnetic body with a magnetic force. | 08-13-2009 |
| 20090208253 | TONER BOTTLE AND IMAGE FORMING APPARATUS - A toner bottle includes a bottle main body for discharging toner contained therein by rotation of the bottle main body and a scraping member disposed inside the bottle main body for rubbing the inner wall surface of the bottle main body 20 by rotation of the bottle main body. A shaft section for supporting a rubbing section included in the scraping member has an inclined support section extending with a predetermined angle inclined in a direction deviating from a direction in which an axis of rotation of the bottle main body extends. | 08-20-2009 |
| 20090285505 | IMAGE PROCESSING METHOD, IMAGE PROCESSING APPARATUS, AND IMAGE FORMING APPARATUS - When a predetermined processing is performed on image data, a target area to be subjected to the predetermined processing in an image based on the image data is received, the predetermined processing is performed only on the target area, a position of a processed image in the target area where the predetermined processing is performed is changed, and the processed image and a non-target image in a non-target area except for the target area are synthesized with each other. When the synthesis is performed, an overlapped area where the non-target image and the processed image overlap with each other is extracted, and processing for reflecting image density data of the processed image and that of the non-target image at a predetermined ratio is performed, with respect to the extracted overlapped area. | 11-19-2009 |
| 20090285605 | TONER REPLENISHING APPARATUS AND IMAGE FORMING APPARATUS - A toner replenishing apparatus is provided. The toner replenishing apparatus includes a toner replenishing container for replenishing toner stored therein to a developing section by a rotation of the container itself, a toner scraping member provided to be movable without being fixed in the toner replenishing container and to rub against an inner wall surface of the container, including a plurality of magnetic bodies arranged in a predetermined direction and a support section that extends in an arranging direction of the magnetic bodies and supports an one end portion of each of the magnetic bodies, and a magnet for attracting the magnetic bodies with a magnetic force, disposed along an outer peripheral surface of the toner replenishing container. | 11-19-2009 |
| 20100003056 | TONER CARTRIDGE AND IMAGE FORMING APPARATUS USING THE SAME - A toner cartridge is provided removably fitted to a toner supply pipe for supplying toner to a developing device. The toner cartridge includes, as a toner discharging mechanism, a toner discharging portion having a toner discharge port, a toner conveyor screw for conveying toner inside toner container and a shutter for opening and closing the toner discharge port. The shutter has a loosening member. When the toner cartridge is fitted to the toner supply pipe, the loosening member moves inside the toner container as the shutter moves along the toner discharge port. | 01-07-2010 |
| 20100226689 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS USING THE SAME - A developing device includes a developing vessel for storing a developer, a first conveying passage, a second conveying passage, a first conveying member and a second conveying member to supply toner to a photoreceptor drum. The first conveying member includes a first rotary shaft and a first multi-helically structured blade. The first multi-helically structured blade includes a first inner helical blade and ring-shaped first outer helical blade. The first inner helical blade is formed so that the radius of the helical blade varies cyclically. The second helical pitch of the first outer helical blade is smaller than the first helical pitch of the first inner helical blade. The first outer helical blade inscribes the outer periphery of the first inner helical blade at its minimum radius portions. | 09-09-2010 |
| 20100322670 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS USING THE SAME - The developing device includes: a developing container for storing a developer; first and second conveying passages that are formed in the developing container and sectioned by a partition; first and second conveying members disposed inside the first and second conveying passages, respectively, to agitate and circulatively convey the developer through the first and second conveying passages in opposite directions; a developing roller that supplies the developer in the second developer conveying passage to a photoreceptor drum; first and second communication paths that connect between the first and second conveying passages at both ends of the partition; and, a developer flow regulator that regulates the flow of developer moving from the first conveying passage to the second conveying passage, in accordance with the height of the developer surface of the developer. | 12-23-2010 |
| 20110026974 | TONER CARTRIDGE AND IMAGE FORMING APPARATUS INCLUDING THE SAME - A toner stirring section provided in a toner cartridge includes a first rotating body and a second rotating body. The first rotating body is rotated around an axis J | 02-03-2011 |
| 20110064481 | TONER CARTRIDGE AND IMAGE FORMING APPARATUS USING THE SAME - A toner cartridge includes a container for containing toner, a toner discharge section having a toner discharge port, an auger screw provided in the container, for conveying toner in the container to the toner discharge section, a shutter for opening and closing the toner discharge port, and a toner flowing-out preventing member provided in a communicating part between the container and the toner discharge section, for preventing flowing out of toner by closing an opening of the communicating part. The toner flowing-out preventing member is configured so as to open the opening in conjunction with an opening operation of the shutter. | 03-17-2011 |
