PURPOSE:To prevent a floating toner from being stuck to a part of a convergent optical conductor, by arranging a transparent film, which can be wound up, between a photoreceptor and the convergent optical conductor. CONSTITUTION:A transparent sheet-shaped film 10 is inserted between a photosensitive drum 1 and a convergent optical conductor 4. This film 10 is wound around shafts 9a and 9b, which are attached rotatably to both sides of the convergent optical conductor 4, to form winding materials 10a and 10b. Film cleaning members 11 consisting of a polyurethane foam or brush are provided on and under the film 10 in both sides of the convergent optical conductor 4 to clean front and rear faces of the film. It is desirable that the film 10 is near the tip of the convergent optical conductor 4. |
