Abstract
A cartridge includes a developing roller rotatable about a rotational axis thereof and a movable lever. A coupling member is operatively connected to the developing roller, with the coupling member being movable, in response to a movement of the lever, between (a) a first position in which the coupling member is exposed to outside of the cartridge, and (b) a second position. The coupling member is provided at a first end portion on a first side of the cartridge. In a direction of the rotational axis of the developing roller, the first position is farther from a second end portion provided on a second side of the cartridge that is opposite to the first end portion on the first side of the cartridge than the second position is from the second end portion on the second side of the cartridge.
