Abstract
In the particular embodiment of the invention described in the specification, selected portions of the surface of a selenium-arsenic layer of a photosensitive element for use in electrophotography are provided with a superfinish having ridges and grooves in the range of 0.1 to 2.0 .mu.m and a width of 3 .mu.m or less by vibrating a grinding stones on the moving surface at a frequency of 1,000 to 1,500 cpm and an amplitude of 3 mm. The grindstone is held against the surface with a pressure of 0.3 to 0.4 kg/cm.sup.2.
Claims5
A photosensitive element for use in electrophotography comprising a photoconductive layer composed of a selenium-arsenic alloy at least at the exposed surface thereof, the exposed surface having a rough surface portion having ridges and grooves in the range from 0.1 to 2 microns in height and 3 microns or less in width created by superfinishing the exposed surface.
