Abstract

PURPOSE:To collect completely a residual toner without damaging a photosensitive drum by providing a spongy roller which contacts to a photosensitive surface, turns freely and contacts to a scaping blade, on the lower part of a cleaning blade. CONSTITUTION:A spongy cleaning roller 8 which contacts to the surface of a photosensitive drum 1, turns freely and abuts to a scraping blade 9 is provided on the lower part of a cleaning blade 2. According to this constitution, a residual toner 6 adhering to the drum 1 is scraped and dropped down by the blade 2, and does not flow out to the outside by adheres to the roller 8 by the roller 8 turning in the direction opposite to the drum 1. Subsequently, the adhering toner is scraped down by the blade 9. In this way, the residaul toner can be collected completely without damaging the photosensitive drum.
