PURPOSE:To enhance sensitivity, durability and light resistance by incorporating crystalline oxytitanium phthalocyanine into a charge generating layer and incorporating a specific compd. into a charge transfer layer. CONSTITUTION:The charge generating layer of the laminated electrophotographic sensitive body contg. a conductive base, the charge generating layer and the charge transfer layer contains the crystalline oxytitanium phthalocyanine and the charge transfer layer thereof contains the compd. expressed by formula I. The crystalline oxytitanium phthalocyanine which has a substituent in the benzene ring or has halogen as a substituent is used as the charge generating agent. The crystal type may be either alpha type and betatype or the mixture composed thereof. The electrophotographic sensitive body having the high sensitivity, high durability and high light resistance is obtd. in this wsay. |
