An electrostatic photoreceptor toner cleaning blade composition comprising an elastomeric matrix containing inorganic filler particulates homogeneously dispersed therein is disclosed. The cleaning blade is fabricated by using a low glass transition thermoset polyurethane whereupon inorganic particulates such as mirco-crystalline silica, fine glass spheres, Mica, Wollastonite, glass fibers, and Basalt fibers are cross-linked by chemical reaction between a polyol prepolymer and a di-isocyanate cross-linker, to form a 3-dimensional cross-linked network.
