Shutter structure for toner refill cartridge
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.
