Abstract

One method of preparing an imaging member having photoconductive material in interlocking continuous paths of the type described in U.S. 3,787,208 (R. N. 3ones) having high gloss working surfaces is to utilize the technique of inverse casting. However, when this technique is used, some method of applying the conductor-based electrode to the top surface must be used in a manner such that degradation

One method of preparing an imaging member having photoconductive material in

interlocking continuous paths of the type described in U.S. 3,787,208 (R. N. 3ones) having high gloss working surfaces is to utilize the technique of inverse casting. However, when this technique is used, some method of applying the conductor- based electrode to the top surface must be used in a manner such that degradation

of the electrical properties of the photoreceptor does not follow. The present concept involves the method of sealing the top surface of an inversely cast organic

matrix photoreceptor of the type described in U.S. 3,787,208 so as not to impair the electrical properties and at the same time seal the surface against electrical degradation. As set forth in the attached figures, Item 1 in Figure 1(a) represents a

temporary substrate of aluminum. Item 2 is an easy-release coating, and Item 3 is the photoconductive layer which is deposited, oven dried and then fused. A key step in the treatment of this inversely cast photoconductive layer is the use of colloidal graphite as an interface sealer 4. A thin layer of graphite provides a

conductive sealer that serves as a base for the more conductive coating 5 which is applied as a conductive lacquer or by other means. This c...
