Abstract
PURPOSE:To bring a developing device and a photosensitive body into speedy contact and noncontact with each other by providing a cylindrical thin film member which is fitted onto a developing roller and guide members which have internal surfaces nearly conforming with the external surface shape of the developing roller and are rotatable on both ends of the developing roller. CONSTITUTION:This device has the developing roller 3, the cylindrical thin film member 2 which has slight surplus length for the peripheral length of the developing roller 3 and are fitted while covering the developing roller, the rotatable guide members 4 which has the internal surfaces nearly confirming with the external surface shape of the developing roller 3 and are arranged on both ends of the developing roller 3, and stopping members 7a and 7b which allow or inhibit the rotation of the guide members 4. The guide members 4 on the developing roller 3 shift in position by the operation of the stopping members 7a and 7b and the position of the surplus part of the thin film member 2 moves. 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.
