发明名称 ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE, PROCESS CARTRIDGE AND DEVELOPING DEVICE USED THEREIN AND TONER RECYCLING METHOD THEREFOR
摘要 PROBLEM TO BE SOLVED: To make toner carrying efficiency high by eliminating need for pushing up recovered toner as much as possible to a toner storage part against gravity, to reduce cost by shortening a recovered toner carrying path and reducing the number of parts and to drive a recovered toner carrying member naturally by shortening the recovered toner carrying path and simplifying the driving of the recovered toner carrying member. SOLUTION: This electrophotographic image forming device equipped with a toner recycling device 36 to restore the recovered toner from a cleaning device 14 to a developing device 12 is provided with a returning port 68 to return the recovered toner recovered by the device 36 to a middle position in the gravity direction of the toner storage part 21 in the device 12, that is, to a lower position in the gravity direction than the upper surface of the toner obtained when the storage part 21 is full of the toner.
