摘要： PROBLEM TO BE SOLVED: To avoid downtime of an image forming apparatus that occurs on waste-toner bottle full detection and to prolong the time at which it is detected that the bottle becomes full of waste toner by efficiently using the capacity of each waste-toner bottle. SOLUTION: The waste toner bottles, each being independently attachable/detachable, are collectively arranged in circle in a rotor that holds the bottles so that they are rotated together. Each waste toner bottle when it is determined by waste-toner full detection that the bottle is full of waste toner is removed from a waste-toner recovery position by the rotation of the rotor. Each is replaced with the adjacent waste-toner bottle that is fresh. COPYRIGHT: (C)2004,JPO
