PURPOSE:To automatically peel a seal by forming a seal for closing a toner discharge hole so as to be peeled and a slide plate loaded slidably in the loading/unloading direction of a case and coupled with the peeling end of the seal. CONSTITUTION:Before the loading of a cartridge 14 into a holder 12, the slide plate 24 is positioned on the toner discharge hole 20 to close the discharge hole 20 by the seal 22. When the cartridge 14 is loaded into the guide groove 26 of the holder 12, the leading end of the slide plate 24 is abutted upon a step part 29 and then a projection 24a formed on the back end of the slide plate 24 is abutted upon a step part 28, so that the slide plate 24 is relatively backed together with the seal 22 and the seal 22 is completely peeled from the opening surface of the discharge hole 20 at the coincidence of the discharge hole 20 with a feed hole 30. Consequently, the periphery of the device can be prevented from staining by toner scattering due to a seal peeling work and the generation of a trouble due to the unpeeled seal can be removed. |
