ABSTRACT:
A cleaning device for an electrostatographic copying machine collects residual toner from a photoconductive surface of the copying machine by the use of fiber-like bristles adhered to a face of a slit through which air is pulled by a vacuum pump. The bristles are pressed gently into sliding contact with the imaging surface and thereby loosens the toner for capture by the vacuum pump through the slit. An alternative would be to use open-cell foam in place of the bristles.
