ABSTRACT:
A toner cartridge includes a first chamber and a second chamber divided by a partition wall. A toner moving member has a screw member that rotates to cause the toner in the first chamber to move. An agitating member includes an agitator bar that agitates the toner in the second chamber. The toner moving member and agitating member are operatively coupled so that one of the toner moving member and the agitating member is driven in rotation, the other of the toner moving member and the agitating member also rotates. The toner moving member is a first screw conveyor. The first screw conveyor spans across substantially half a length of the first chamber.
