Abstract
A developing cartridge includes a developing frame body rotatably supporting a developing roller. A first end member is attached to the first end of the developing frame and a second end member is attached to the second end of the developing frame body. The first end member and the second end member are rotatable independently of each other and relative to the developing frame body about a rotational axis common to the first end member and the second end member, and with rotation of the developing frame body relative to the first end member and the second end member, the developing roller moves from a first position to a second position in a direction that crosses a position of an axis of the developing roller when the developing roller is in the first position.
