A developing apparatus includes a developing roller for developing an electrostatic latent image formed on a photosensitive member. A drive transmission member is provided at one end of the developing roller for receiving a driving force and transmitting the driving force to the developing roller. The developing apparatus also includes an urging member, provided at other end of the developing roller, for urging the developing roller. An abutting portion is abutted by the shaft of the developing roller by an urging force of the urging member to position the developing roller with respect to the axial direction of the developing roller, and a contact member contacts a peripheral surface of the shaft of the developing roller to apply a voltage to the developing roller.
