ABSTRACT:
In association with a blade cleaning arrangement supported for chiseling removal of toner from a charge retentive surface, an auger is provided to move toner to the edge of the charge retentive surface and simultaneously simulate a foam roll cleaner, known to have good abrasive characteristics in the presence of toner. An auger member having a roughened or sharpened surface in contact with a charge retentive surface is arranged slightly upstream and adjacent to a blade cleaning arrangement for the removal of residual toner accumulating adjacent to a cleaning blade after release from a charge retentive surface such as a photoreceptor in a reproduction machine. The auger member may be comprised of a foam material providing an abrading surface roughness. Other augering members simulate the abrading qualities of the foam roll cleaner, such as for example, a sharpened auger edge which lightly scrapes the charge retentive surface, or an auger of a polymeric material, with a roughed surface.
