摘要

A toner cartridge is supported on a supporting apparatus and includes a chamber that holds toner therein. A shutter has a first engagement portion and is slidably mounted on the toner cartridge and is configured to open and close the opening. A second engagement portion is formed on a body of the toner cartridge. The supporting apparatus includes a supporting surface that supports the toner cartridge thereon. A first limiting element limits movement of the toner cartridge in an insertion direction of the toner cartridge. A stopper limits movement of the shutter in the insertion direction when the toner cartridge is inserted into the supporting apparatus. A second limiting element engages the first engagement portion and the second engagement portion to limit movement of the toner cartridge in a pull-out direction of the toner cartridge and movement of the shutter in the pull-out direction.
