PROBLEM TO BE SOLVED: To surely prevent toner bridging at a drop path without increasing the number of parts, as for an electrophotographic image forming device for removing the residual toner on an image carrier after transferring an image to a paper, and then, recovering the toner through the drop path. SOLUTION: A carrying screw 30 for carrying the residual toner removed from the photoreceptor to the entrance of the drop path 35 is arranged in a cleaning device. An eccentric part 31b is formed on the shaft 31 of the carrying screw, and the eccentric part is fitted into the drop path 35, and a hook 40c is hung on the eccentric part 31b so to arrange a toner bridge preventing member 40 in the drop path 35. And, the rotation of the carrying screw 30 is converted to the reciprocative movement so as to be transmitted to the toner bridge preventing member 40, then, the toner bridge preventing member 40 is reciprocatively moved in the toner direction, and also, the member is moved vertically and horizontally in a direction vertical to the drop direction. |
