Wetting by toners of the surface of reusable photoconductors in electrophotographic processes results on image cycling in adhesion of the toner to the photoconductor surface to form a film. Such filming is reduced or eliminated by including in the developer a small amount of certain unpigmented organic polymeric materials having smaller particle size than the pigmented toner particles. Suitable organic polymers are fluorinated hydrocarbon polymers and copolymers, and polyethylene.
