Patent ID: 8515308

Claim:
An image forming apparatus comprising: a latent-image carrier that carries a latent image; a first support body that supports the latent-image carrier; a first gear that is rotatably supported by the first support body and is rotated by driving force from a driving unit; a developing body that develops the latent image on the latent-image carrier; a second gear that transmits rotational force from the first gear to the developing body by mesh with the first gear; a second support body that rotatably supports the developing body and the second gear, the second support body being movable relative to the first support body in a direction such that the second gear moves away from the first gear; an arc-shaped face provided in the second support body and centered on an axis of the second gear; and an arc shaped restricting portion provided in the first support body, centered on an axis of the first gear, the arc shaped restricting portion restricting the movement of the second support body relative to the first support body by contact with the arc-shaped face.
