Abstract

Blade cleaning of belt photoreceptors requires some type of support near the blade tip at the opposite side of the photoreceptor. It is desirable to provide the part of the support that contacts the belt with a low friction surface. For a production cleaner, the blade can be fabricated from an aluminum extrusion which is anodized and then impregnated with polytetrafluoroethylene. Other materials such as nickel phosphorous can be impregnated with polymers to provide a support with the desired low friction properties. Another embodiment comprises porous bronze sintered into the surface of the support with an overlayer of polytetrafluoroethylene lead.
