Abstract

In an electrostatographic image reproducing apparatus, particularly one having a selenium photoreceptor material imaging surface developed with particulate toner material, and having a cleaning blade deformably engaging the imag~ ing surface to clean the toner therefrom, the improvement wherein the imaging surface has a uniformly and continu~ ously roughened surface with a surface roughness pattern averaging 3 to 5 microns in lateral dimensions, but not substantially exceeding 20 microns in lateral dimensions or 2 microns in depth. This roughness pattern reduces friction between the cleaning blade and the imaging sur~ face, in comparison to a smooth imaging surface, without adversely affecting image reproduction or providing toner trapping sites in the surface, The surface pattern is preferably formed by etching a conductive metal substrate with the desired surface roughness pattern and overcoating it with a thin uniform layer of the photoreceptor material,
