Patent ID: 7361439

Claim:
A multi-layered photoreceptor comprising: a roughened substrate having an average roughness (R a ) of about 0.080-0.200 μm, no fewer than about 200 peaks and valleys over a 0.8 mm length with a peak to valley distance of at least about 0.100 μm, and about 0 peaks and valleys over a 0.8 mm length with a peak to valley distance of at least about 0.400 μm; an oxidation layer formed on the roughened substrate; an undercoat film formed on said substrate; a charge generating layer formed over the undercoat film; and a charge transport layer overlaying said charge generating layer, wherein said multi-layered photoreceptor is suitable for use in xerographic printers capable of producing print output substantially free of distortions due to axial streaking in the undercoat film.
