Abstract: Disclosed is a novel overcoating material for electrostatographic photoreceptors. The composition comprises an organic, crosslinkable, polymeric composition having dispersed therein a particulate, wax-like, normally solid, low molecular weight tetrafluoroethylene telomer. Application of the composition to an electrostatographic photoreceptor to form a thin uniform layer results in improvement in copy quality and reduction in surface friction of the device. When the photoreceptor employs a selenium/arsenic alloy as the photoconductor, print deletions normally associated with the photoconductor are eliminated.

Abstract: An apparatus and process are provided for removing contaminants from the surface of an electrostatic imaging member. The apparatus includes elements for cleaning the surface to remove toner particles and other particulate materials therefrom, and elements for removing the contaminants from the surface after it has been cleaned by the cleaning elements. The contaminant removal elements comprise at least one brush which moves relative to the surface wherein the brush exerts a normal force per unit fiber against the surface of at least two milligrams. A reproducing apparatus and process are also provided.
