An improved cleaning apparatus for a copying machine includes, in addition to a conventional magnetic brush-type device in which a rotatable sleeve partially immersed in developer surrounds a group of magnets, a magnetic member disposed immediately upstream of the normal cleaning position at which the magnetic brush sleeve is brought into predetermined proximity with the photosensitive member. The magnetic member is located closely adjacent the surface of the photosensitive surface so that residual developer particles remaining on the photosensitive surface are magnetically attracted to the magnetic member prior to and for the purpose of supplementing conventional magnetic brush cleaning immediately downstream therefrom.
