Patent ID: 8649724

Claim:
A cleaning system comprising: a composite photoreceptive imaging member having a support layer, an electrically conductive layer interfacing with the support layer, a photoconductive charge generation layer interfacing with the electrically conductive layer and generating charge holes and electrons in response to exposure to electromagnetic radiation; a charge transport layer that allows charge holes to migrate from the charge generation layer to an outer surface of the imaging member while resisting migration of electrons from the charge generation layer to the outer surface; and a cleaning blade member having a cleaning surface layer against the outer surface to at least in part remove toner and debris from the outer surface; wherein the cleaning surface layer has a first material and a second material that are combined in proportions that cause a triboelectric charge to be formed on the outer surface having a difference of potential of between zero and minus 20 volts to be generated between the outer surface and a ground.
