Abstract
A rotary element is rotatably attached to a cartridge main body, which is attachable to and detachable from a developing apparatus. The rotary element has an opening/closing portion for a toner outlet formed in the main body, a toner-collecting portion for collecting the toner housed in the main body, and a joint connectable to a rotation driving element provided on the developing apparatus. When the main body is detached from the developing apparatus, the outlet opening/closing portion is pressed against the periphery of the outlet. By rotation of the rotary element, the toner-collecting portion collects the toner in the main body. The toner collected is supplied to the developing apparatus via the outlet.
