Disclosed are electrophotographic imaging members comprising a supporting substrate with at least one electrophotographic imaging layer and an imaging surface wherein the imaging surface includes parallel ridges and valleys across the width of the imaging member. The parallel ridges and valleys on the imaging surface mimic the surface characteristics and roughness of a multiplicity of seamed or lap joined junctions used in the manufacture of endless belted photoreceptor devices. Thus, the ridges and valleys on the imaging surface, for example as shown in FIG 1 and FIG 2, respectively, for belt and d r d r o l l type photoreceptors, when used in conjunction with a blade cleaner in doctor mode with at least some fraction of blade tuck, provides enhanced blade cleaner performance and prevents the formation of "comet" deposits. Comet deposits may result from a build up of a combination of toner impacted onto the photoreceptor and loose magnetite particles found in magnetite containing toners.
