Summary:PURPOSE:To obtain always good and uniform images at the time of starting the use of a photosensitive body by incorporating conductive powder and/or conductive resin into a cleaning blade and/or film sheet. CONSTITUTION:This drum unit has at least the electrophotographic sensitive body 1 and the cleaning blade 3 and/or the film sheet 4 in contact with the photosensitive body 2. The cleaning blade 3 and/or the film sheet 4 contains the conductive powder and/or the conductive resin in such a case. Namely, rubber materials and the foamed bodies thereof as well as foamed bodies of various kinds of synthetic resins are used as the constituting materials of the cleaning blade 3 and/or the film sheet 4. The potential difference between the surface of the photosensitive body 2 and the cleaning blade 3 and the film sheet 4 is hardly generated even if the friction between the photosensitive body 2 and the cleaning blade 3 and the film sheet 4 by the vibration and impact at the time transportation and vibration arises. The generation of static electricity is thus prevented.
