Abstract
A photoreceptor for electrophotography has a substrate, charge-generation layer and a charge-transport layer, with either one of the charge-generation layer and charge-transport layer being a top OPC layer formed from a paint. The top OPC layer contains a surfactant having a perfluoroalkyl radical in an amount between 0.01% and 1% by weight of a solid ingredient of the paint. The surfactant functions for prevention of reduction in film thickness and occurring of flaws on the top OPC layer caused by abrasion after iterative operation of the photoreceptor.
Claims11
A photoreceptor for electrophotography comprising a substrate and at least one photoconductive (OPC) layer formed on said substrate and having a charge-generation function and a charge-transport function, said at least one OPC layer including a top layer containing a surfactant in an amount between 0.01% and 1% by weight of solid ingredient in said top layer, said surfactant having a perfluoroalkyl radical, and said surfactant having been exuded to a surface of said top layer of said at least one OPC layer.
