A cleaning member (16) for cleaning an open/close mechanism (14) for opening/closing a supply port (1a) of a toner cartridge (1) is moved in sync with operation of the open/close mechanism. The cleaning member (16) is in contact with the open/close mechanism (14) for scraping the toner from the outside surface of the open/close mechanism (14), thus preventing the toner from dirtying the unit, etc. when the toner cartridge (1) is removed.
