ABSTRACT:
A moving magnet cleaner for scraping excess toner off a photoreceptor surface. The moving magnet cleaner provides carrier bristles for brushing the photoreceptor surface. The sweeping of the moving magnet cleaner past the photoreceptor provides a self-leveling of the carrier bristles to the size of the distance between the cleaner roll and the photoreceptor surface. A toner roll rotates in proximity to the cleaner roll to transfer toner from the carrier particles to the toner roll and also provides self-leveling of the carrier bristles. The carrier for the magnet cleaner is continually replacedwith carrier from a sump and the moving magnet cleaner exhibits a large cleaning zone allowing for gentle removal of the toner from the photoreceptor.
