Abstract
PURPOSE:To improve the cleaning efficiency and at the same time to prolong greatly the lifetime of a cleaning member, by setting a magnetic member and a toner recovering roll at the lower part of a cleaning roll containing a porous elastic matter fixed to a cylindrical permanent magnet. CONSTITUTION:A magnetic member 6 is set within a range of the magnetic sucking force of a cleaning roll 3 that contains a cleaning member 5 made of a porous elastic matter on the surface of a cylindrical permanent magnet 4. At the same time, a toner recovering roll 7 having a permanent magnet 9 is set into a sleeve 8. The toner 2 stuck on the surface of the roll 3 is detached at the position near the roll 7 and by the repulsion of the same polarity and dropped into a recovering container 11. The toner scattered in the opposite direction is adsorbed to the sleeve 8 and then collected to the container 11 through a scrape-off plate 10. As a result, the cleaning efficiency is improved and the lifetime of the member 5 is greatly prolonged since the roll 3 has just a light touch to a photoreceptor 1.
