20090110447 | IMAGE FORMING APPARATUS AND ELECTRIC DISCHARGE DEVICE - An image forming apparatus includes a diode for restraining deterioration of an electric discharge device caused when a voltage applied to a discharge electrode and a shield electrode is switched. By switching the voltage at only one position using the diode, both of the voltage applied to the discharge electrode and the voltage applied to the shield electrode can be switched simultaneously. | 04-30-2009 |
20100158582 | ION GENERATING DEVICE, CHARGING DEVICE, AND IMAGE FORMING APPARATUS - An ion generating device is arranged such that a heater electrode is wired so as to heat (i) a creeping discharge area and (ii) areas where respective terminal sections of an induction electrode, a discharge electrode, and the heater electrode are provided. This allows prevention of dew condensation and nitric acid generation in the vicinities of the respective terminal sections. | 06-24-2010 |
20110033211 | IMAGE FORMING METHOD - An image forming method using toner comprising toner particles having a core-shell structure comprising a core particle incorporating a viscous material and a shell layer covering the above core particle is disclosed. The method comprises steps of a toner image forming step on a dielectric drum; a first pressure applying step in which the shell layer of the toner particles forming the toner image is subjected to a preliminary break treatment by a first pressure roller, which is arranged in contact with the dielectric drum; and a transfer/fixing step in which a toner image made by the toner particles which have been subjected to a preliminary break treatment by the first pressure applying step is transferred and fixed to an image support by a second pressure roller which is arranged in contact with the dielectric drum. | 02-10-2011 |
20110033212 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image bearing member for carrying a toner image; a transfer member forming a nip with the image bearing member to transfer the toner image from the image bearing member onto a transfer material at the nip, wherein the image forming apparatus is operable in a marginless printing mode in which the toner image formed on the image bearing member is larger than a size of the transfer material, and the toner image is transferred as far as edges of the transfer material; and a charging member for effecting electric discharge toward the image bearing member, the charging member being disposed at such a position as is opposed to a side of the transfer material which receives the toner image in an upstream side of the nip with respect to a feeding direction of the transfer material, wherein when the apparatus operates in the marginless printing mode, the charging member effects the electric discharge toward the toner existing in an area of the image bearing member which corresponds to an area which is outside beyond the edge of the transfer material at the nip to electrically charge the toner in the outside area to a polarity opposite a regular polarity. | 02-10-2011 |
20110052274 | DEVICE FOR PREPARING A RECORDING MEDIUM FOR TRANSFER PRINTING TONER IMAGES IN AN ELECTRO-PHORETIC PRINTING SYSTEM - An electrophoretic printing system is provided comprising a transfer printing station for transfer printing charge images developed with liquid toner comprising a carrier fluid and toner and wherein the developed charge images are transferred to a recording medium. A wetting unit provided adjacent to the recording medium before the transfer printing station as viewed in a movement direction of the recording medium wets the recording medium with a fluid. | 03-03-2011 |
20120008990 | METHOD TO OPTIMIZE THE TRANSFER OF DEVELOPER FLUID ONTO A PRINTING SUBSTRATE IN AN ELECTROPHORETIC PRINTING APPARATUS - In a method to optimize transfer of a developer fluid on a printing substrate in an electrophoretic printing apparatus, a developer fluid containing at least carrier fluid and toner particles is used, the toner particles having sizes that are greater than diameters of capillaries in a surface of the printing substrate. The additive particles are added to the developer fluid before the transfer, sizes of the additive particles being selected such that the sizes are smaller at least in part in comparison to the diameters of the capillaries in the surface of the printing substrate. | 01-12-2012 |
20120237271 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image bearing member, an image forming unit for forming a toner image and a toner pattern comprising toner not to be transferred onto a recording medium for adjustment of a density of toner on a surface of the image bearing member, a nip forming member contacting the surface of the image bearing member to form a transfer nip therebetween, a transfer bias applicator for applying a transfer bias in which an alternating current component and a direct current component are superimposed to transfer the toner image onto the recording medium in the transfer nip, a first cleaning device to mechanically remove toner remaining on the image bearing member after passing through the transfer nip. The transfer bias applicator applies a charge eliminating bias to remove charge from toner in the toner pattern when the toner pattern passes through the transfer nip. | 09-20-2012 |
20130114981 | IMAGE-RECORDING METHOD - An image-recording method includes steps of supplying an intermediate transfer medium with a liquid composition containing a reaction agent that makes a coloring material contained in ink precipitate or aggregate, forming an intermediate image by supplying the ink to at least a portion of the area of the intermediate transfer medium to which the liquid composition has been supplied, and transferring the intermediate image to a recording medium. The liquid composition contains a particulate silicone rubber. | 05-09-2013 |
20130149013 | IMAGE FORMING APPARATUS - In an image forming apparatus, a voltage applied to a pre-transfer charger is set to the highest voltage, and is then reduced at a position corresponding to a predetermined range from a leading edge of a recording material, to suppress a phenomenon of backward scattering of toner formed just before entering a transfer nip, when a burr formed on the leading edge of the recording material exits the transfer nip. | 06-13-2013 |
