ABSTRACT:
A sheet-shaped regulation member is supported by a supporting unit with an elastic force occurring by bending a sheet-shaped regulation member in the longitudinal direction thereof, and a force received as a result of being pressed by a developing roller. Thus, direct contact can be securely made onto a developer bearing member, and a regulation member can be provided which enables easily attaching thereof to the supporting member, as well as enabling a developing apparatus, processing cartridge, and image forming apparatus, to be reduced in size.
