Developer accommodating unit, process cartridge and electrophotographic image forming apparatus

摘要

A developer accommodating unit includes a flexible developer accommodating container sealed with a sealing member at its developer discharging opening; a rotatable unsealing member for removing the sealing member from the opening; a drive transmission member for transmitting a rotational force to the unsealing member, wherein the drive transmission member is mounted at one longitudinal end portion of the unsealing member and is rotatably assembled with a frame; and a supporting member for supporting the unsealing member when the unsealing member is assembled. The supporting member includes a preventing portion for preventing the unsealing member from dropping from the supporting member. In a state in which the drive transmission member is assembled with the frame, a gap between the unsealing member and the supporting member is larger than a gap between the drive transmission member and the frame. The unsealing member is spaced from the supporting member.
