PURPOSE:To obtain an electrophotographic sensitive body low in residual potential and high in sensitivity by laminating an electrostatic charge generating layer contg. a trimethine dye and a charge transfer layer contg. poly-N-vinylcarbazole or its deriv. on a conductive substrate. CONSTITUTION:The charge generating layer contg. a trimethine dye and the charge transfer layer contg. poly-N-vinylcarbazole or its deriv. are laminated on the conductive substrate, such as a plate of aluminum, or the like metal or a plate of tin oxide, or the like. The electrophotographic sensitive body is obtained by drying this laminate and further heat treating it at 100-120 deg.C for >=30min. A preferable film thickness of the charge generating layer is 0.2-2mum, and that of the charge transfer layer is 5-20mum. Ordinary plasticizers may be added to both of the charge generating layer and the charge transfer layer in order to enhance flexibility, mechanical strength, etc., of the coat film. |
