Abstract

A contact for use in contacting a moving photoreceptor surface, is formed from a structure (preferably a pultrusion) including a plurality of continuous strand fibers of high electrical resistance, and a thermally stable insulating component between the resistive fibers. The resistive fibers are configured to form a brush extending from the insulating component for contact with the photoreceptor surface. The resistance of the fibers is sufficiently high to reduce leakage of surface charges away from the photoreceptor and to provide a high resistance between adjacent fibers. The insulating component, which serves to interface the carbon filaments from each other and from a host polymer may comprise an organic compound, such as a polyimide composition, or may comprise an inorganic compound such as Al2 O3 or water glass, and is thermally stable below about 1000° C. The host polymer, on the other hand volatilizes rapidly and cleanly upon direct exposure to laser energy.
