20100266316 | TRANSFERRING AND FIXING DEVICE FOR PERFORMING FIXATION SIMULTANEOUSLY WITH TRANSFER - A transferring and fixing device includes an image carrier member to hold an unfixed toner image, a heat member to heat the unfixed toner image on the image carrier member, a pressure member which comes in press contact with the image carrier member, nips a recording medium with the image carrier member, and presses and conveys the recording medium, and a vibrating member to transmit vibrations to the recording medium passing through between the image carrier member and the pressure member. | 10-21-2010 |
20110079545 | SHEET SORTING AND STORING APPARATUS AND SHEET SORTING AND STORING METHOD - According to one embodiment, a sheet sorting and storing apparatus includes: an ID recognizing unit configured to recognize a user ID for identifying a user; a sheet storing unit including plural reuse sheet storing spaces each provided to correspond to the user ID recognized by the ID recognizing unit; a sheet inserting unit into which a sheet is inserted; a printing detecting unit configured to detect whether a front side and a rear side of the sheet inserted into the sheet inserting unit are printed; and a sheet directing unit configured to direct, as a reuse sheet, a one-side-unused sheet detected by the printing detecting unit as not being printed on one of a front side and a rear side to the reuse sheet storing space corresponding to the user ID recognized by the ID recognizing unit and store the sheet in the reuse sheet storing space. | 04-07-2011 |
20110287358 | FIXING DEVICE - A fixing device includes a fixing belt including a metal layer, a pressing member to form a nip between the pressing member and the fixing belt, an induction current generating coil that faces an outer periphery of the fixing belt, and heats the fixing belt located at a nip position through a hollow inside of the fixing belt, and a coil controller supplies a high frequency to the induction current generating coil. | 11-24-2011 |
20120141175 | IMAGE FORMING APPARATUS AND IMAGE FORMING AND ERASING METHOD - An image forming apparatus according to an embodiment includes: an image erasing section including a first member which has an elastic layer and heats a recording medium having a thermally decolorizable toner image on the toner image side and a second member which erases the toner image by allowing the recording medium in cooperation with the first member; an image forming section which transfers a thermally decolorizable toner image onto the recording medium on which the toner image is erased to form an unfixed toner image; and an image fixing section including a third member which does not have an elastic layer and heats the recording medium on the unfixed toner image side and a fourth member which fixes the unfixed toner image by allowing the recording medium in cooperation with the third member. | 06-07-2012 |
20120308278 | FUSER FOR EQUALIZING TEMPERATURE OF HEAT GENERATING SECTION - According to one embodiment, a fuser includes a fixing belt including a conductive layer, an induction-current generating section to electromagnetically induction-heat the conductive layer, an opposed section to form a nip in cooperation with the fixing belt, an auxiliary heat generating section electromagnetically induction-heated by the induction-current generating section, and a moving section to move the auxiliary heat generating section with respect to the fixing belt. | 12-06-2012 |
20130004218 | FUSER, IMAGE FORMING APPARATUS, AND IMAGE FORMING METHOD - Certain embodiments provide a fuser including a cylindrical fixing belt, a heating unit configured to heat the fixing belt, a pressurized section, a first nip forming section, a second nip forming section, and a moving mechanism. The pressurized section is arranged in contact with the fixing belt. The first nip forming section is fixed in a position where the first nip forming section presses the fixing belt against the pressurized section. The second nip forming section is configured to be movable between a position where the second nip forming section can press the fixing belt against the pressurized section and a position where the second nip forming section is separated from the fixing belt. The moving mechanism moves the second nip forming section. | 01-03-2013 |
