The toner pipe has a discharge port configured to discharge toner in the toner pipe. The toner container includes a toner discharge port, a toner reception port, and a toner conveyor. The toner discharge port discharges toner in the toner container. The toner reception port receives toner discharged from the discharge port of the toner pipe. The toner conveyor conveys toner from the toner reception port toward the toner discharge port. A development housing includes a development reception port and a development discharge port. The development reception port receives toner discharged from the toner discharge port. The development discharge port discharges, to the toner pipe, toner that is retuned from the development housing to the toner container.
