PURPOSE:To simplify the peeling of a seal material by folding one end of the seal material sealing an opening section to the inside to form an end section, further folding the seal material on the opposite side, and using this portion as a pulling end section in a cartridge main body storing the developing powder and having the opening section for supply. CONSTITUTION:An opening is provided on a cartridge main body 11 from the upper face to one end section oppositely to the fitting/removing section on the developing device main body side, a seal material 13 is provided to seal it, and the seal material 13 is peeled when a toner 14 stored inside is supplied to the developing device side. One end section 13a of the seal material 13 is folded by 180 deg. to the inside from the portion fixed to one end face 11a of the main body 11, the other end section 13b is likewise folded by 180 deg. from the portion fixed to the other end face 11b of the main body 11, and it is overlapped on the end section 13a. When the main body 11 is exchanged, the end section 13b is pulled, the overlapped portion 15 is displaced in the pulled direction, and the peeling is facilitated due to the small friction force of it. |
