Document Type and Number:
Japanese Patent JP4086547
Kind Code:
B2
Abstract:
A developer cartridge (9) has a first chamber (B) that holds fresh toner and a waste toner chamber (C) that holds waste toner. The toner cartridge (9) includes a partition (18) that divides an inner space of the toner cartridge(9) into the fresh toner chamber (B) and the waste toner chamber (C). The partition(18) is such that the fresh toner chamber (B) and the waste toner chamber (C) extend substantially in parallel with each other and are partially adjacent to each other horizontally. The partition (18) operates in such a way that the fresh toner chamber (B) decreases in volume and the waste toner chamber (C) increases in volume with increasing amount of the waste toner in the waste toner chamber (C). The movable portion may be a deformable bag-shaped member (18b). The fresh toner chamber (B) may have a resilient flap(22) therein to agitate the fresh toner.
