Abstract
A toner supply container includes a rotatable container body and a sealing member provided at its axial end portion. The sealing member is movable in an axial direction and includes a sealing portion to seal and unseal an opening of the container body when in first and second relative positions, respectively, and a coupling portion positioned to receive a rotational drive force for rotating the sealing member and the container body. The coupling portion includes an elastically displaceable supporting portion, an engaging portion, and a displacing force receiving portion, which are integrally molded. The engaging portion includes a rotational force receiving portion for receiving a rotational drive force for rotating the sealing member and the container body, and a locking portion. The displacing force receiving portion is provided on the supporting portion at a position closer to the container body than the engaging portion.
