A process cartridge case including a toner hopper, and a discharged toner box disposed at both sides of a drum housing accommodating a photoconductive drum. The process cartridge case is separable into first and second parts at a border in a region of the drum housing. Legs are provided on an outer surface of the toner hopper so that the process cartridge can be placed in an upright position during a refilling operation. An agitator extends beyond a side wall in a cantilever fashion to allow a box with a bearing member to rotatably support the agitator shaft. An elastic member is included in the box to hermetically seal the agitator shaft and prevent toner leakage.
