Abstract
A photoreceptor includes a supporting substrate and an outer layer on the photoreceptor, the outer layer including silicone oil uniformly dispersed as vesicles in a continuous film forming polymer matrix. This photoreceptor is used in a xerographic copier/printer machine and contributes to a longer operating life of the machine by providing continuous lubrication, decreased friction and decreased wear of the interaction of the photoreceptor and other machine parts. This photoreceptor is prepared by incorporating silicone oil and at least one film forming polymer in at least one solvent, removing the solvent and forming a dried outer layer in which the silicone oil is phase separated from the other components of the top layer forming small vesicles which are uniformly dispersed in the continuous film forming polymer matrix. The silicone oil provides lubricity to the outer surface of the photoreceptor without adversely affecting print quality and this lubricity is renewed throughout the life of the photoreceptor.
