Abstract

An image forming apparatus configured such that a cartridge that stores a developer is attachable to and detachable from the image forming apparatus includes a rotary that is rotatable and that is configured to store the developer supplied from the cartridge; a tray that removably supports the cartridge and that moves with respect to the rotary to a retraction position in which the cartridge is located outside the rotary and to a mount position in which the cartridge is located inside the rotary; and a control unit that controls the movement of the tray. In a case that an elapsed time since the tray is located at the retraction position exceeds a predetermined length, the control unit controls the movement of the tray such that the tray moves from the retraction position to the mount position.
