| 20100008701 | IMAGE FORMING APPARATUS, DEVELOPING DEVICE AND DEVELOPER DISCHARGE MECHANISM - In order to provide an image forming apparatus capable of maintaining the image quality by making smooth flowability of a surplus developer, which is discharged according to supply of a new developer (toner and carrier), toward a collection box, there are provided a stirring screw that electrify toner by stirring the toner together with a carrier; a casing that supports the stirring screw and stores a developer in which the toner and the carrier are mixed; a inlet used to supply the developer to the casing; a guide that guides the surplus developer discharged from the casing downward; and a reciprocating member that moves on a flow surface of the guide along which the surplus developer flows. | 01-14-2010 |
| 20100054765 | DEVELOPING DEVICE - A developing device includes a developer tank that contains a developer including a toner and a carrier, a developing agent supplier that develops a latent image by using the toner contained in the developer tank, a discharge port that is provided in a side surface of the developer tank and discharges the developer, and a discharge assisting member that protrudes from a downstream side of the discharge port in a direction of flow of the developer in the developer tank and in a direction crossing the direction of the flow of the developer. | 03-04-2010 |
| 20110142474 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - According to one embodiment, an image forming apparatus includes an image forming unit configured to form a toner image on a first surface of a medium, a fixing unit configured to have a heating member which heats the first surface of the medium, and a pressurizing member which is pressed in contact with the heating member via the medium to heat a second surface of the medium, and a supply unit configured to supply a used medium to the image forming unit, a control unit configured to, when the used medium is supplied from the supply unit, control a fixing setting temperature of the pressurizing member to a temperature equal to or lower than a temperature for fixing on the unused medium, and control a fixing temperature of the heating member to a temperature equal to or higher than a temperature for fixing on the unused medium. | 06-16-2011 |

| 20090052951 | DEVELOPING ROLLER, DEVELOPING APPARATUS, AND IMAGE FORMING APPARATUS - A developing roller according to the invention includes a columnar magnet roller, and a cylindrical sleeve that houses the magnet roller. A plurality of fragmented micro recesses is formed on the surface of the sleeve. The micro recesses are arranged dispersively both in an axial direction and in a circumferential direction of the sleeve. | 02-26-2009 |
| 20090080916 | XEROGRAPHIC COPYING APPARATUS AND METHOD OF CHECKING TROUBLE POINT IN THE SAME AND COMPUTER PROGRAM - In a method of checking a trouble point in a xerographic copying apparatus of the invention, a sequence code is selected from a plurality of sequence codes to distinguish a plurality of sequences to stop an operation of the xerographic copying apparatus in any one process of a plurality of print processing processes for print output of a sheet, an operation of a photoconductor in a state where toner is attached is stopped in any one process among the plurality of print processing processes in accordance with the sequence corresponding to the selected sequence code, and any one trouble point is checked, and therefore, the point where a poor image is generated is suitably grasped. | 03-26-2009 |
| 20090129796 | IMAGE FORMING APPARATUS - There are provided a control unit which controls image quality maintenance, a detection unit which detects a print command of image data, a calculation unit which calculates a print ratio of the image data when the print command for printing at least a predetermined number of sheets is detected, and a toner specific concentration control unit which sets toner specific concentration for each print of the plural sheets on the basis of the print ratio calculated by the calculation unit. | 05-21-2009 |
