Abstract

A developer cartridge is attachable/detachable to/from an image forming apparatus. The image forming apparatus has a rotary containing the cartridge; and a control unit to control the drive unit to rotate the rotary. The control unit rotates the rotary to a first rotational phase for replacing the cartridge; rotates the rotary to a second rotational phase when developing an image; and rotates the rotary in the first rotational phase so as to pass through a third rotational phase more than once and then reach the second rotational phase when performing an image forming operation for a first time after the cartridge is replaced. When the rotary is located in the third rotational phase, the direction from the discharge opening of the cartridge toward the receiving opening is a downward direction.
