PROBLEM TO BE SOLVED: To surely prevent toner leakage form a connecting part between a waste toner discharging port 64 and a waste toner feeding port 98 with a simple structure. SOLUTION: In this device, a regulation part 96b formed on a supporting member 54 regulates the shifting direction of a shutter member 76 in the direction at a specific angle of with respect to an axis A of a straight pipe 48. Therefore, when the force F0 is energized from a coil spring 88 with respect to the shutter member 76, respective component forces F1 and F2 of the force F0 is applied to the shutter member 76, and the component F3 thereof in the direction perpendicular to the axis A is applied in the turning direction with respect to a straight pipe 48. Accordingly, the waste toner discharging port 64 is opened and simultaneously the straight pipe 48 is turned, and the waste toner discharging port is pressed to the waste toner feeding port 98 of the developing device. |
