摘要：
A sealing member seals an opening provided at one axial end of a rotatable container body of a toner supply container detachably mountable to an assembly of an image forming apparatus having a hollow cylindrical driving member. The sealing member includes a sealing portion provided at a side adjacent the container body to seal the opening, and a coupling portion provided at a side remote from the container body to receive a rotational drive force. The coupling portion includes a supporting portion provided on the sealing portion, an engaging portion provided at a free end of the supporting portion, and a displacing force receiving portion provided closer to the container body than the engaging portion. The engaging portion includes a rotational force receiving portion being abuttable in a circumferential direction of the driving member, and a locking portion being abuttable in an axial direction of the driving member.
