Classification: CPC G | IPC G

Claim 21:
22. A cartridge comprising:
a frame;
a photosensitive drum supported by the frame, the photosensitive drum being rotatable about an axis thereof, and the photosensitive drum having a first end and a second end that is opposite to the first end;
a developing roller supported by the frame, the developing roller being configured to develop a latent image formed on the photosensitive drum, and the developing roller being rotatable about an axis thereof;
a coupling positioned at the first end of the photosensitive drum, the coupling being configured to receive a driving force for rotating the photosensitive drum; and
a lever movably supported by a part of the frame at a position that is adjacent to the first end of the photosensitive drum, the lever being movable between a first position and a second position,
wherein, as viewed along the axis of the photosensitive drum, an end of the lever is a first distance from the axis of the photosensitive drum when the lever is in the first position, and the end of the lever is a second distance from the axis of the photosensitive drum when the lever is in the second position, with the second distance being greater than the first distance,
wherein, as measured in a direction of the axis of the photosensitive drum, (i) the end of the lever is a farther distance from the second end of the photosensitive drum than the coupling is from the second end of the photosensitive drum, and (ii) the part of the frame that movably supports the lever is a farther distance from the second end of the photosensitive drum than the coupling is from the second end of the photosensitive drum, and
wherein, as viewed along the axis of the photosensitive drum when the lever is in the first position, the axis of the photosensitive drum is positioned between the lever and the axis of the developing roller.
