Abstract: A photosensitive drum is rotatably supported in a main body. A developing cartridge is detachably mountable on the main body in a state where the photosensitive drum is supported in the main body. The developing cartridge includes a developing device and a frame. The developing device includes a developing roller disposed in confrontation with the photosensitive drum to supply developer to the photosensitive drum when the developing cartridge is mounted in the main body, and a developer-accommodating portion configured to accommodate developer. The frame includes a waste-developer-accommodating portion configured to accommodate waste developer and supports the developing device that is movable relative to the frame. The frame is disposed on an opposite side of the developing roller from the photosensitive drum. An urging member is disposed between the frame and the developing device to urge the developing roller toward the photosensitive drum.

Abstract: A sheet feeding device having sheet feed tray configured to support multiple sheets be movably inserted to a main body. A sheet feed roller is configured to contact the sheet supported by the sheet feed tray and rotate to apply a feeding force to feed the sheet in a sheet feed direction. The sheet feed roller is configured to contact the sheet feed tray when there is no sheet on the sheet feed tray. A push latch mechanism is arranged on a downstream side with respect to the sheet feed roller in the sheet feed direction. A state of the push latch mechanism is alternately switched between an engaged state and a disengaged state every time when a pressing force is applied to the push latch mechanism. A first spring is configured to exert an elastic force to move the sheet feed tray toward a near side.

Abstract: An image forming apparatus is provided. The image forming apparatus includes a chassis having a first opening on a first side, a cover, movable between an open position and a closed position, a plurality of photosensitive members, an intermediate transfer belt, a plurality of primary transfer members, a secondary transfer roller, a first feed roller, a cleaner device, a waste toner container, which is removably installed in the chassis through the first opening and settled in a position opposite from the plurality of photosensitive members across the intermediate transfer belt, to store residual toner collected by the cleaner device, a connector, a first feeding path, a second feeding path, and a second feed roller. The second feed roller is rotatably supported by the cover and movable along with the cover to yield the first opening to the waste toner container when the cover is in the open position.

Abstract: A sheet feeding apparatus includes a first drive roller and a second drive roller disposed downstream of the first drive roller and configured to rotate at a peripheral speed greater than a peripheral speed of the first drive roller. The first drive roller includes a drive shaft and a roller portion. The roller portion is configured to contact the sheet and is movable relative to the drive shaft in an axial direction and a rotation direction of the drive shaft. One of the drive shaft and the roller portion of the first drive roller includes a protrusion protruding toward the other one of the drive shaft and the roller portion. The other one of the drive shaft and the roller portion of the first drive roller includes a recessed portion. The recessed portion includes a peripheral wall that defines an opening such that the protrusion is positioned in the opening.
