Abstract

PURPOSE:To bring a developing device and a photosensitive body into contact and noncontact with each other speedily without moving the whole developing device by providing a cylindrical thin film member fitted onto a developing roller and a press-contacting member which abuts on its surface. CONSTITUTION:This device consists of the developing roller 3 which is driven to rotate, the cylindrical thin film member 2 which has slight surplus peripheral length for the peripheral length of the developing roller 3, and abutting members which are provided in front of and behind the development area of the developing roller 3 and abut on the surface of the thin film member 2. Then the abutting member consists of an eraser 6 and a control roller 4 capable of rotation control. The surplus part of the thin film member 2 shifts in position by the stop and rotation of the developing roller 4. Consequently, the developing device and photosensitive body are brought into easy and speedy contact and noncontact with each other without moving the whole developing device.
