Abstract

PURPOSE:To improve cleaning effect by incorporating a magnetic field generating means in a nonmagnetic body of revolution having flocked conductive brushes. CONSTITUTION:A cleaning device 6 has a rotary brush body 9, which removes residual toner directly from the surface of a photosensitive drum 1, in a casing 8. This brush body 9 consists of a nonmagnetic rotary sleeve 10, many conductive brushes 11 flocked on the surface of the sleeve 10, and a magnet 12 fixed in the rotary sleeve 10 as a magnetic field generating means. The magnet 12 may be made rotatable. The conductive brushes 11 are grounded through the rotary sleeve 10.
