Apparatus for cleaning dry residual toner from the photoconductive surface of a xerographic type copying machine for reuse. The apparatus comprises a wiper blade disposed across the path of operating movement of the photoconductive surface with the wiping edge thereof in physical contact therewith. The wiper blade is supported on a carriage movable in a direction generally longitudinal of the blade. A driver is provided to slowly oscillate the carriage together with the wiper blade back and forth to improve blade cleaning action and wear, and reduce the tendency for toner and other foreign matter to become trapped under the blade. A control means is provided to operate the carriage driver while the photoconductive surface is moving and thereafter up to a short interval.
