Abstract
A cartridge includes a developing roller rotatable about a rotational axis thereof. A frame is configured to support the developing roller. A lever is connected to the frame, with the lever being movable relative to the frame, and a part of the lever protruding beyond the frame. A surface of the developing roller extends a longer distance in a direction of the rotational axis than a distance that the lever extends in the direction of the rotational axis.
