  • Photoconductor member with bound silicone oil
    Publication number: 20060183041
    Abstract: A charge transfer layer system that encapsulates or surrounds high viscosity silicone oils (polysiloxanes) using silicone microspheres, fluoropolymers such as polytetrafluoroethylene or inorganic particles such as silica, or metal soaps (zinc stearate). The encapsulation of the silicone oil results in aggregation or agglomeration of the silicone microspheres, fluoropolymers, or inorganic particles. The silicone oils have viscosity greater than 10,000 centistokes (cs) and the particles are about 6 ?m or less.
