PROBLEM TO BE SOLVED: To cope with compaction, to prevent structure from getting complicated, to obtain excellent stirring and mixing performance for toner and to improve image quality. SOLUTION: A used toner refluxing operating part 11 making used toner drop by gravity is formed on the upper wall 1a of a cartridge main body 1A in which unused toner T is stored, and a toner stirring means 12 and a toner supply means 13 supplying mixed toner to a developing device 2 are disposed in the main body 1A. Thus, the toner is sufficiently mixed and stirred at the main body 1A side without depending on the device 2 side, while preventing the main body 1A from getting large. Since the used toner (t) is made to drop by the gravity, especially, take-in structure for the toner (t) is simplified. The mixing work of the used toner (t) with the unused toner T is efficiently performed regardless of the motion direction of the stirring means 12. |
