DEVELOPER ACCOMMODATING UNIT, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS

The invention relates to a developer accommodating unit, a process cartridge, and an image forming apparatus. The developer accommodating unit includes a frame that has an opening for discharging a developer, and a sealing unit that has a sealing portion for sealing the opening, in which a state of the sealing unit is capable of changing from a first state in which the sealing portion seals the opening to a second state in which the opening is opened. A tip of a first part is positioned on a downstream side of the base of the first part in a first direction if the sealing unit is in the firststate, and the first part is deformed such that the tip of the first part is positioned on an upstream side of the base of the first part in the first direction if the state of the sealing unit changes from the first state to the second state. 本发明涉及显影剂容纳单元、处理盒和成像装置。显影剂容纳单元包括框架和密封单元，框架具有用于排出显影剂的开口，密封单元具有用于密封开口的密封部分，其中密封单元的状态能够从密封部分密封开口的第一状态变为开口打开的第二状态。如果密封单元处于第一状态，第一部分的末端位于第一部分的基部的第一方向的下游侧，并且如果密封单元的状态从第一状态变为第二状态，第一部分变形使得第一
