Developer charging unit, developing device, image-forming apparatus, and computer system

摘要

A developer charging unit comprises a developer charging member for charging developer bore by a developer bearing member by abutting against the developer bearing member; a supporting member for supporting the developer charging member; and a plurality of fixing portions for fixing the developer charging member and the supporting member together, the fixing portions being lined up according to a predetermined arrangement. A spacing between two of the fixing portions located in a central section in a longitudinal direction of the developer charging member is shorter than a spacing between two of the fixing portions located at an end section in the longitudinal direction of the developer charging member.
