PURPOSE:To prevent residual toner from staying between the front end part of a blade and the surface of a photosensitive body and to clean the surface of the photosensitive body completely by forming the suction opening of a toner sucking device in front of the front end part of the blade in the rotating direction of the photosensitive body. CONSTITUTION:The suction opening 6 of the toner sucking device 5 is formed in front of the front edge of the blade 1 to have a thin and long opening part which is as wide as the blade 1, and residual toner 3 which collides against the front edge of the blade 1 is separated from the surface 2 of the photosensitive body according to the rotation of the photosensitive body 4 shown by an arrow and floats temporarily, so that the toner is sucked into the suction opening 6 of the toner sucking device 5. This sucked residual toner 3 is sucked to the suction part 8 through a duct 11, collected in a filter bag 9, and treated. |
