PURPOSE:To obtain the titled material having improved flexibility and sticking property against a substrate by incorporating an org. photoconductive substance and a phenoxy resin to the titled material. CONSTITUTION:The titled material contains the org. photoconductive substance and the phenoxy resin. The electrophotographic sensitive body is formed by coating a substrate body which is composed of a polyester film and has a deposited layer of In2O3, with a solution A, followed by drying it with a hot air to remove a solvent contd. in the solution A, thereby forming an electric charge generating layer having 1mum thickness, and subsequently by coating said layer with the solution B, followed by similarly, removing the solvent contd. in the solution B, thereby forming an electric charge transfer layer having 20mum thickness. Said solution A is formed by mixing 3g of copper phthalocyanine, 2g of the phenoxy resin, 1g of polyisocyanate and 70g of a mixture of MEK/toluene (1/1), and by dispersing the obtd. mixture for 24hr. Said solution B is formed by dissolving 2g of polycarbonate and 2g of diphenyl hydrazone derivative in 10g of THF. Thus, the titled material having an excellent flexibility and very good sticking property against the substrate body, and capable of preventing a lowering of a photosensitivity is obtd. |
