Abstract
A toner cartridge extending in a longitudinal direction thereof has a fresh toner chamber and a water toner chamber. The fresh toner chamber and waste toner chamber extend parallel to each other so that the fresh toner chamber and the waste toner chamber are aligned in a direction perpendicular to the longitudinal direction. The waste toner chamber incorporates a toner-conveying member such as a screw conveyor. The screw conveyor extends between the opposed longitudinal ends, and causes the waste toner to move further into the waste toner chamber. The waste toner chamber has an entrance formed therein through which waste toner is received from a print process cartridge. The entrance opens yieldably when a waste toner exit enters the waste toner chamber through the entrance and closes when the waste toner exit moves out of the enters the waste toner chamber.
