PURPOSE:To prevent the developer from being scattered by constituting the container of a hopper-like container body, a receiving plate, an unsealing piece for covering its opening part so as to be peelable and a shutter, and constituting the container so that it can be unsealed after it is attached to a developing machine, when it is used as a hopper. CONSTITUTION:A container body 1 is fastened to a female screw 27 of a receiving plate 2 with a male screw 15 and an opening part 23 is sealed up tightly by sticking the flat supporting surface 21 to a part 31 of an unsealing piece 3 with a peeling adhesive agent. Also, a shutter 4 is engaged to both end parts 22a, 22b of the receiving plate so as to be attachable and detachable and protects a film for covering the opening part. At the time of use, the shutter 4 is removed from the receiving plate 2 and inserted into a developer supply part, positioned correctly by an engaging hole 28, and thereafter, peeled off gradually from a rear end 24 of the receiving plate by drawing out a turn-back part 32 of the unsealing piece 3, and the opening part23 is unsealed without scattering a developer to the periphery. Also, with respect to a use container, as well, by drawing it out into the shutter 4, scattering of a residual developer can be prevented. |
