An image forming apparatus.

摘要

An image forming apparatus includes image bearing member; a device for forming an electrostatic latent image on the image bearing member; a developing device for developing a latent image formed on the image bearing member, the device including a developing unit having a developer carrying member for carrying thereon and supplying a developer to the image bearing member; a moving device for moving the developing unit between an operative position and a non-operative position away therefrom; a supporting member for supporting the developing unit for rotation about an axis, the supporting member rotatably supporting the developing unit at one side and supporting the developing unit at the other side for rotation and movement in a predetermined direction; an urging device for urging the developing unit toward the image bearing member adjacent the other side; a driver for applying driving force to the developer carrying member of the developing unit; wherein when the developing unit rotates to be set to the operating position, and the driver is operated, the developing unit is urged toward the image bearing member about the axis.
