PURPOSE:To facilitate unsealing and a removal of a seal without contaminating a hand and clothes, by using a seal unsealing auxiliary member having a space for containing after unsealing, at the time of unsealing of a seal member of a developer cartridge, and also, executing the unsealing itself by suing an unsealing member. CONSTITUTION:From a developer containing vessel 2, only an unsealing auxiliary member 12 is drawn out to this side, and before the engagement of both of them is detached, its drawing-out operation is stopped, and only a housing 8 is installed to an image forming device body. Also, when an unsealing member 13 is drawn out to this side, a left frame part 39 allows force in the right direction to work on a free part 11, while coming into contact in a form of extending and racking the free part 11 of a seal member 10, and the seal member 10 for sealing up tightly an opening 6 is peeled off gradually from the inner part of the vessel 2. In such a way, a developer which has been contained in a developer storage space 4 is thrown into a developing device, and the seal member 10 is contained as it is in an internal space 15 of the auxiliary member 12. In such a way, a hand and clothes are not contaminated. |
