摘要： A developing apparatus includes a developer carrying member for carrying a developer thereon. An electrostatic image is formed on an image bearing member with the developer. A rotatable developer electrifying member contacts the developer carrying member and electrifies the developer carried on the developer carrying member. A holding member supports the developer electrifying member and the developer carrying member. A bearing assembled to the holding member receives a shaft of the developer electrifying member. The developer electrifying member is held by the holding member through the bearing member.
