A sheet feeding device and an image forming apparatus including an auxiliary pusher section, disposed at a sheet loading plate, for pushing one end of each sheet loaded on a rotatable sheet loading plate towards a sheet feeding section. The auxiliary pusher section includes a pusher member for contacting each of the sheets, and a spring for biasing the pusher member towards the sheet feeding section. The auxiliary pusher section pushes the sheets against the sheet feeding section to allow reliable feeding of the sheets.

Sheet feeding device

An image bearing member, process device acting on the image bearing member, a first frame, a second frame lockable and separable with respect to the first frame, a locking body and a locking member lockable to the locking body, provided to separably interlock the first and second frames, and a recessed portion and a projection fittable into the recessed portion which are provided to separably interlock the first and second frames. With above construction it is possible to provide a process cartridge, an image forming system, and a method for assembling a cleaning device, which can be easily assembled and can sufficiently cope a large when the number of re-cycles.

Process cartridge mountable in an image forming system and a method for

A process cartridge includes a first frame in which a toner containing unit for containing toner used for a developing operation and a charger unit are mounted, and a second frame which can be engaged by and disengaged from the first frame, and in which an image bearing member, a developing unit and cleaning unit are mounted. With this arrangement, the assembling ability and disassembling ability are improved remarkably, and the process cartridge is suitable for the re-cycling to contribute to the protection of the earth-environment.

Process cartridge and image forming system on which process cartridge is

A process cartridge detachably mountable to a main assembly of an image forming apparatus, includes a plurality of process device including at least one member having an electrically conductive cylinder; a supporting frame for supporting as a unit the plural process devices; and an electrode, in the supporting frame, having a first portion electrically contactable to the main assembly and a second portion press-contacted to an end surface of the cylindrical member.

Process cartridge and image forming apparatus using same

A sheet feeding device includes a sheet accommodation unit for supporting a plurality of sheets, the sheet accommodation unit being movable between waiting and sheet feed positions, an urging device for urging the sheet accommodation unit toward the sheet feed position, a sheet feed device for sending out the sheets supported by the sheet accommodation unit at the sheet feed position, a moving device for moving the sheet accommodation unit between the waiting and sheet feed positions, a driving force transmitting device for transmitting a driving force of moving the sheet accommodation unit to the moving device when engaged with the displacing device, a release device for releasing the engagement of the displacing device with the driving force transmitting device, and a locking device for cancellably restricting the moving device when the engagement of the moving device with the driving force transmitting device is released by the release device.

A process cartridge detachably mountable to an image forming apparatus includes a device contributable for forming an image; a developer accommodator; and a sealing member between the image forming device and the developer accommodator, wherein the sealing member is provided by injecting a liquid material which becomes an elastomer when it is solidified.

Process cartridge detachably mountable to image forming apparatus

A reciprocating driving device is provided with a reciprocating moving member supported to be movable in a predetermined direction and the reverse direction. A first rack is provided on the reciprocating moving member, and a second rack is provided on the reciprocating moving member and arranged so as to face the first rack. A gear moves the reciprocating moving member in the predetermined direction or the reverse direction by rotating in a predetermined direction, selectively meshing with the first rack or the second rack.

Reciprocating driving device

An image fixing apparatus includes a heater; an endless film through which a toner image on a recording material is heated by heat produced by the heater; and a controller for controlling a position of the endless film in a direction perpendicular to a rotating directon of the endless film.

Image fixing apparatus with movable film and means for controlling film

An image fixing apparatus includes a heating device, a non-endless film movable together with a toner image supporting medium, wherein the toner image on the supporting medium is heated by the heating device through the film, a rewinding device for rewinding the film in a direction opposite to a movement direction of the toner image supporting medium, and a pressing device for press-contacting the film to the heating device and to the image supporting medium, wherein the rewinding device rewinds the film while the pressing device does not perform its pressing operation.

Image fixing device and image forming apparatus with same

A variable magnification image forming apparatus includes a photosensitive member, a light source, projecting device for forming and projecting on the photosensitive member an image of the original illuminated by the light source, the projecting device including lens system movable in accordance with a magnification of projection selected, a first limiting member for limiting light rays disposed with a fixed positional relation with respect to the lens system, and a second limiting member for limiting light rays in the lens system, the second limiting member being displaceable in a direction different from a direction of an optical axis of the lens system in accordance with magnification change to change the positional relation with respect to the first limiting member.
