Toner particles removed from the photoreceptor surface by the cleaner brush are dislodged from the brush bristles upon contact with a flicker rod to which an air flow regulating plate is fixed and efficiently carried by air flows, through proper gaps, air passages or a slit, into the filter section in which a filter is enclosed. | |
