Abstract
Abstract The invention provides an electrophotographic laminated film and a method for producing the electrophotographic laminated film. The electrophotographic laminated film comprises a substrate and at least one of a coating layer and a function control means provided on a surface of the substrate. The uppermost layer of the coating layer has a surface resistance in a range of 1.0×10 8 to 1.0×10 13 Ω/□. The surface of the substrate preferably comprises at least one of a polycarbonate resin and a polyallylate resin. At least one of the coating layer and the function control means is preferably formed by providing a coating liquid. Further, a solvent contained in the coating liquid is preferably permits at least one of the coating layer and function control means to be formed while dissolving the surface of the substrate.
