Abstract

PURPOSE:To prevent damaging of the surface of a moving member by so constituting a titled device that a magnetically attracting means is provided and that the residual magnetic material is removed from the surface of the moving body by this. CONSTITUTION:A magnet roller 27 having magnetism is disposed in proximity to the photoconductor layer 1 formed on the outside circumferential surface of a photosensitive drum 2. An endless belt 29 is put on this roller 27 and a roller 28. Now, when the layer 1 left and stuck with magnetic material on its surface upon ending of transfer is turned to the inside of the magnetic field of the roller 27 by rotation of the drum 2, the magnetic material stuck on the drum surface is attracted by the magnetic force of the roller 27 and is moved onto the surface of the belt 29. The material which does not react with the magnetic force is scraped off onto the belt 29 by a blade 20 of a scraping member, and is transferred into a receiving member 30. With such constitution, the damaging of the surface of the moving member is prevented.
