Support part, developer container, process cartridge and electrophotographic image forming apparatus

摘要

The present invention provides a support part (16) attached to a developer container used in an electrophotographic image forming apparatus, comprising a support portion (16b) for supporting one end of an agitating member (10f) for agitating developer contained in the developer container, a fitting portion (16b) fitted into a through hole formed in a frame of the developer container, a detent portion (16a) for preventing the support part from disengaging from the through hole, a seal member (17) contacting portion for contacting with a seal member for preventing developer from leaking from between the frame and the support part, and a driving force receiving portion (16d) for receiving a driving force for rotating the support part. In a direction intersecting with an axis of the support part, the detent portion is positioned inwardly of an outer peripheral surface of the seal member contacting portion.
