Abstract
A charge transport layer material for a photoreceptor includes at least a polycarbonate polymer binder having a number average molecular weight of not less than 35,000, at least one charge transport material, polytetrafluoroethylene particle aggregates having an average size of less than about 1.5 microns and a fluorine-containing polymeric surfactant dispersed in a solvent mixture of at least tetrahydrofuran and toluene. The dispersion is able to form a uniform and stable material ideal for use in forming a charge transport layer of a photoreceptor. The resultant charge transport layer exhibits excellent wear resistance against contact with an AC bias charging roll, excellent electrical performance, and delivers superior print quality.
