20110206423 | IMAGE FORMING APPARATUS - An image forming apparatus includes: a first image carrier; a first image forming unit that forms an image; an intermediate transfer belt; a primary transfer unit that primarily transfers the image onto the intermediate transfer belt; a secondary transfer unit that secondarily transfers the image transferred further onto a recording medium; a second image carrier that transfers the image onto the recording medium; a second image forming unit that forms an image on the second image carrier; a direct transfer unit that directly transfers the image onto the recording medium; a recording medium carriage belt, and a driving roller that drives the recording medium carriage belt; a speed fluctuation detecting unit; and a drive control unit that controls driving of the driving roller so as to reduce the cyclic speed fluctuation of the carriage belt based on a detection result of the speed fluctuation detecting unit. | 2011-08-25 |
20110206424 | FIXING APPARATUS - A fixing apparatus for fixing an image formed on a recording material, the fixing device includes a guiding member for guiding movement of the recording material, provided in a recording material passing opening of the apparatus; a rib projecting from a recording material passing surface of the guiding member, for being contacted by the recording material; a shutter provided at a position opposing the guiding member and movable between a position for opening the passing opening and a position closing the passing opening, and a projection provided at a position of the shutter opposing a position of the guiding member not having the rib with respect to a direction perpendicular to a recording material feeding direction, wherein when the shutter takes the closing position, a clearance between the rib and the shutter is larger than a clearance between the guiding member and the projection. | 2011-08-25 |
20110206425 | IMAGE FORMING APPARATUS - A disclosed image forming apparatus includes an image carrier; a developing device configured to form a toner image on the image carrier; a compressed air generating unit configured to generate compressed air; an air nozzle configured to eject the compressed air; a fixing device configured to fix the toner image on a sheet, the sheet being separated from the fixing device by the compressed air ejected from the air nozzle to the sheet; a pressure regulation unit provided between the compressed air generating unit and the air nozzle; and a guide path connected to the pressure regulation unit and configured to guide excess air generated by a pressure regulation of the pressure regulation unit to at least one part in the image forming apparatus. | 2011-08-25 |
20110206426 | BELT PRESSURIZING DEVICE AND IMAGE FORMING APPARATUS - A belt pressurizing device includes: an endless belt that is circularly driven; a pressing member that presses the endless belt against a facing member with the endless belt interposed between the pressing member and the facing member; and a lubricant supplying member that supplies lubricant to reduce sliding resistance of the endless belt pressed by the pressing member, so as not to be in contact with the endless belt. | 2011-08-25 |
20110206427 | Fixing device and image forming apparatus incorporating same - A fixing device includes an endless fuser belt, a contact member, a pressure member, a heater, a heater support, and a belt tensioner. The endless fuser belt is looped into a generally cylindrical configuration extending in an axial direction thereof. The contact member extends in the axial direction inside the loop of the fuser belt. The pressure member extends in the axial direction with the belt interposed between the contact member and the pressure member. The pressure member is pressed against the contact member through the fuser belt to form a fixing nip. The heater is disposed inside the loop of the fuser belt to heat the fuser belt. The heater support is disposed inside the loop of the fuser belt to hold the heater in position. The belt tensioner is disposed inside the loop of the fuser belt to tighten the fuser belt. | 2011-08-25 |
