PURPOSE:To obtain the org. photosensitive body which is of a positive charge system and has high sensitivity and excellent durability by providing a charge transfer layer contg. high-polymer materials consisting of a specific molecular structure. CONSTITUTION:The high polymers expressed by the formula I are used as the org. photoconductor material by the positive charge system. In the formula I, R denotes a bivalent cyclic substituent contg. a pi electron conjugation system and n denotes >=2 integer. All these high polymers have the high electron transfer power and the characteristics as the excellent photosensitive body are attained by combining the high polymers as a charge transfer material for positive charge with a suitable CG material (charge generating material). Since the high polymers have the film formability, the CT layer (charge transfer layer) can be formed without requiring a binder resin. Since the photosensitive body operates in the positive charge system in this way, the generation of the ozone to deteriorate the characteristics of the photosensitive body is substantially prevented and since the high polymers have the high thermal stability, the CT layer having the excellent durability is formed. |
