PROBLEM TO BE SOLVED: To prevent toner from scattering in the case of detaching either of a toner replenishing device or a developing device from an image forming device main body. SOLUTION: In the case of detaching the toner replenishing device from the device main body, a shutter 37 is closed cooperatively with the detaching operation, then, an elastic member 38 arranged in a shutter part 37a is fitted to a toner discharge port 32a so as to tightly close the toner discharge port 32a, then, the toner T is prevented from flowing out. Simultaneously, the toner T sticking to the inner peripheral surface of the toner discharge port 32a is scraped by the elastic member 38 so that the toner T may fall to the toner entrance 28a, then, the toner T is prevented from scattering. |
