发明名称 IMAGE FORMING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide an image forming device having a simple-structured recovered-toner-carrying means capable of securely carrying recovered toner without exerting pressure on it and being subject to the constraint of a positional relationship between a cleaning part and a developing part and also capable of separating and removing impurities, such as paper powder and so on, during carrying. SOLUTION: In an image forming device, a carrying member 41 for carrying recovered toner in a cleaner to a developing device 20 has a cylindrical rotary member having a magnetic force spirally and an abutting member 43 abutting the rotary member, the rotary member having a portion 41A having a magnetic force and a portion 41B having no magnetic force. Thus, without the constraint of a positional relationship between the cleaner and a developing part, the recovered toner can be returned from the cleaner to the developing device. Also, because the recovered toner is carried with a magnetic force by use of the carrying member, pressure is not exerted on the recovered toner. Accordingly, a toner agglomeration is not formed, and also the toner can be carried without causing a toner spout from a recycled-toner carrying part.
