ABSTRACT:
A toner cartridge and a process cartridge, individually, have a shutter which makes sliding movement by opening and closing their toner inlet and toner outlet. When those cartridges are attached to a color printer and fixed together by a fixing lever, the shutters of both cartridges and the fixing lever can move together as one. When they make sliding movement together, both of the shutters are opened and toner supply becomes available. There are thus realized a toner cartridge, a process cartridge, an imaging cartridge, and an image forming apparatus to which those cartridges are attachable, all of which can prevent toner leakage from both a toner housing portion and a process portion and enables even an unaccustomed user to attach each cartridge without making surroundings dirty.
