PURPOSE:To remove the toner remaining on the surface of a photosensitive drum satisfactorily and to recover the same satisfactorily by disposing a non- return material on the surface of the drum without contacting therewith and providing a pocket part which reserves a toner between the non-return member and a rubbing body. CONSTITUTION:The edge part 4 of a rubbing body 3 is formed with acute angle on the scraping side of a toner 2 by notching the surface in proximity to a photosensitive drum 1 side diagonally. A scraping surface 6 notched to approximately an arc shape is formed on the scraping side of the body 3. Further, a non-return material 15 is disposed on the scraping side of the body 3 along the surface of the drum 1 without contacting with said surface. The material 15 is a belt-like material having a certain thickness and is supported so as to maintain a small clearance 17 between the surface of the drum 1 and the opposite surface facing the same by a supporting shaft 16. Thus the remaining toner is recovered satisfactorily. |
