Abstract:
An image forming apparatus includes: a photosensitive drum; a toner cartridge having a toner supply port; and a developing unit including: a developing roller; a developing frame; and a conveyance portion capable of conveying toner contained in the toner cartridge to the developing frame. The conveyance portion including: a coupling tube capable of being coupled to the toner cartridge and having a toner receiving port that faces the toner supply port in a state where the coupling tube is coupled to the toner cartridge; a conveyance tube fixed to the developing frame, the conveyance tube being movable with respect to the coupling tube, in a state where the coupling tube is coupled to the toner cartridge and the toner receiving port faces the toner supply port; and a shutter movable between an open position and a closed position.

Claim (Index 1):
A process cartridge comprising:\n a toner cartridge having a toner supply opening; and a drum unit including:\n a photosensitive drum extending in a first direction; and \n a developing unit including:\n a developing roller extending in the first direction, the developing roller having a first end and a second end spaced apart from the first end in the first direction; \n a developing frame having a first side wall and a second side wall spaced apart from the first side wall in the first direction, the first side wall for supporting the first end of the developing roller, the second side wall for supporting the second end of the developing roller; \n a tube having a toner receiving opening that faces the toner supply opening in a state where the toner cartridge is attached to the drum unit, the tube extending in a second direction crossing the first direction, the tube positioned at the first side wall of the developing frame; \n a conveyance member extending in the second direction, at least a part of the conveyance member being positioned inside the tube; and \n a first shutter movable from a first closed position at which the toner receiving opening is closed to a first open position at which the toner receiving opening is opened in response to movement of attaching the toner cartridge to the drum unit.
