A cleaning system has 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 the outer surface 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 electrostatic surface to at least in part remove toner and debris from the outer surface. 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.

An electrophotographic printer includes a rotatable photoreceptor adapted to receive dry toner and a rotatable toning member arranged with respect to the photoreceptor to supply toner thereto. A seal includes a complaint contact member and a non-contact member. The contact member is arranged in mechanical contact with the photoreceptor. The non-contact member is spaced apart from the surface of the toning member by a selected non-zero distance, the selected distance being greater than zero. This reduces dusting.
