PROBLEM TO BE SOLVED: To make a sealing member which hermetically seals the discharge port of a toner container to freely open/close maintain stable attaching strength even with the lapse of time and under any environment and keep hermetically sealing property and to prevent soiling around the toner discharge port caused by the adhesion of toner. SOLUTION: In this toner replenishing container freely attached to/detached from an electrophotographic image forming device, an aperture part for discharging the toner is double cylinders 1a and 1b, and the sealing member 2 sealing the aperture part is press-fit and engaged with the inner surface of the inside cylinder and seals the outside cylinder, and further a locking part 2b provided on the member 2 is engaged with the part to be locked 1g of the outside cylinder 1b so that the member 2 is locked in a pulling-out direction. |
