An image forming unit includes a cylindrical rotatable image carrier that holds an electrostatic latent image, a cylindrical rotatable developer carrier that develops the held electrostatic latent image on the image carrier, and a cylindrical rotatable developer supplying member that supplies a developer to the developer carrier. Distance controlling members control the distance between axes of the image carrier and the developer carrier. A developer carrier gear is fixed on the developer carrier. A developer supplying member gear is fixed on the developer supplying member. A cylindrical rotatable idle gear engages with the developer carrier gear and the developer supplying member gear. A link member maintains constant the distance between rotational axes of the developer supplying member and the idle gear. Another link member maintains constant the distance between rotational axes of the developer carrier gear and the idle gear. A connecting member connects the two link members. |
