Abstract
An image forming apparatus includes a toner cartridge which is attachable to and detachable from a rotary through the opening of the body frame and is movable to an attached position where a discharge opening faces an inlet opening such that a toner storage portion and a developing storage portion communicate with each other via the discharge opening and the inlet opening and a retracted position where the toner cartridge is retracted from the attached position, with respect to a storage frame. In addition, one or more motors (i) move the toner cartridge from the attached position to the retracted position and (ii) rotate the rotary with the toner cartridge about a rotation axis between (ii-1) a developing posture in which a developing roller faces a photosensitive drum and (ii-2) a replacement posture in which detachment of the toner cartridge from the rotary is allowed. The toner cartridge is configured such that at least part of the toner cartridge projects outside the body frame in a state in which the toner cartridge is at the retracted position.
