Endless photosensitive body

Abstract

Abstract PURPOSE:To prevent thoroughly the photofatigue of a photosensitive body by coating the surface of the photosensitive body by a light shieldable protective sheet of which one end overlaps on top of the other end, guiding the superposed part to a fixing device in the stage of mounting the photosensitive body and stripping the protective sheet by the fixing device so that the photosensitive body can be exchanged without exposing the photosensitive surface of the photosensitive body to external light. CONSTITUTION:An endless photosensitive belt 1 is constituted with an endless photosensitive belt body 2 and the light shieldable protective sheet 3 covering the photosensitive surface. More specifically, a conductive film formed by forming an aluminum film on a polyester film by vapor deposition is used for the substrate of the body 2. To mount the belt 1 to the copying machine, the operator opens the door of the copying machine to open the inside of the copying machine body, removes the deteriorated old photosensitive belt from a winding member 6 and mounts the belt 1 by directing the superposed part of the light shieldable protective sheet to above and below and the front end part thereof toward the fixing device 7 side. The operator closes all the doors, etc. of the copying machine to avoid the entry of the external light to the inside of the copying machine body and operates a switch for exchanging the belt of the copying machine.
