The toner chamber 1 extends in the axial direction of the circumferential surface. The process cartridge is also provided with a stirring bar 2 that is disposed in the toner chamber 1 and that rotates centering around a rotary shaft parallel with the axial line of the circumferential surface, an engaging member 2e suspended to pivotally move at a part of the bar 2, a shutter mechanism having a shutter member 2b capable of moving from a closing position where it closes the window 1b to an opening position where it opens the window 1b and also capable of rotating centering around the rotary shaft and a guide 6 for guiding the member 2e when the bar 2 is rotated. |
