PROBLEM TO BE SOLVED: To reduce resistance caused by the rubbing of an elastic seal and a shutter around the toner discharge port of a toner cartridge and to prevent the turn-up of the elastic seal. SOLUTION: A plate member 12f3 is stuck to the elastic seal 12f5 around the toner discharge port 12f1, and a toner seal 12f2 is stuck to the member 12f3. When the seal 12f2 is broken before opening a shutter 12f4, the member 12f3 is brought into contact with the shutter 12f4 by the elastic force of the seal 12f5. The shutter 12f4 and the member 12f3 are rigid bodies and slide slightly. It is enough to prepare the small squeeze margin of the elastic seal. |
