Abstract

Residual toner is removed from the photoconductive layer 25 of a xerographic drum by a rotatable brush 49 which deposits fluorinated hydrocarbon material which is stated to reduce the build-up of a toner film. The brush fibres may be of fluorocarbon resins e.g., polytetrafluoroethylene, polyvinylfluoride, polyvinylidenfluoride, polychlorotrifluoroethylene, copolymers of tetrafluoroethylene with tetrafluoropropylene. A fibrous web may be used in place of the brush. A rod 53 removes toner particles from the brush which are then drawn by vacuum means to a filter bag 52.
