Abstract: A printer may include a main body and a development cartridge attachable to and detachable from the main body. The development cartridge may comprise a developing portion in which a photoconductive drum and a developing roller are provided, a waste toner container to receive waste toner removed from the photoconductive drum, a toner container connected to the developing portion and to receive toner, and a toner refilling portion connected to the toner container and to refill toner through the toner refilling portion into the toner container. The printer may include a communicating portion provided in the main body to be connected to the toner refilling portion to provide an access the toner refilling portion from outside of the main body when the development cartridge is attached to the main body.

Abstract: A toner cartridge includes a body including a first toner discharge portion, a discharge shutter configured to rotate relative to the body about a first rotation axis to a discharge position at which toner is allowed to be discharged via the first toner discharge portion and a closed position at which the first toner discharge portion is closed, and a locking member supported by the body and configured to rotate about a second rotation axis different from the first rotation axis to a locked position at which a first interference portion of the discharge shutter located at the closed position is caught by a second interference portion, thereby not allowing the discharge shutter to rotate and an unlocked position at which the discharge shutter is allowed to rotate.
