PURPOSE:To obtain a copy having stable image quality for along period by using a polymer formed by blending a specific arom. polycarbonate resin with a bisphenol polycarbonate resin as the binder polymer of a charge transfer layer. CONSTITUTION:The polymer formed by blending the arom. polycarbonate resin expressed by the formulas 1, 2 is used as the binder polymer of the charge transfer layer. In the formula 2, X, X' denote a hydrogen atom, halogen atom or methyl group, R denotes a hydrogen atom, halogen atom, hydroxyl group, carboxyl group, acetyl group or alkyl group of 1-5C. The ratio of the resin expressed by the formula 2 in the binder polymer is adequately 10-90wt%, more particularly preferably 40-60wt%. The crystallization resistance of the charge transfer by the solvent used for coating the upper layer is thus improved and the generation of a solvent crack is obviated as well. Such photosensitive body is provided with the electrical characteristic exactly equal to the electrical characteristic of the photosensitive body for which ordinary bisphenol polycarbonate is used alone. |
