Subsequent to the transfer step, the magnetic toner which attaches to the surface of the photosensitive member is removed therefrom by a cylindrical brush, then transferred to a non-magnetic sleeve which internally houses a magnet, and finally scraped therefrom by a separator to fall down into a tray.
