Abstract
An image forming apparatus includes a photosensitive drum, a developing device including a developing roller and a developing frame including a toner receiving port, and a toner cartridge including a toner accommodation part and a conveyance device configured to convey toner from the toner accommodation part toward the developing device. The conveyance device includes a coupling tube and a shutter. The coupling tube includes a toner supply port faceable the toner receiving port, is coupleable to the developing device and is movable with respect to the toner accommodation part at a state where the coupling tube is coupled to the developing device and the toner supply port faces the toner receiving port. The shutter is movable between an opening position at which the toner supply port is opened with the coupling tube being coupled to the developing device and a closed position.
