PURPOSE:To obtain a photosensitive body having high sensitivity and excellent repetitive characteristics in positive and negative electric charge by providing a photosensitive layer contg. a specific pyrazoline compd. to said body. CONSTITUTION:The photosensitive layer contg. at least one kind among the pyrazoline compds. expressed by the formula I is provided to the photosensitive body. In the formula, R1, R2 respectively denote a substd. or unsubstd. aryl group., X denotes the formula II or formula III. n Denotes 0, 1, 2, 3, 4 or 5 integer. R3-R15 respectively denote a hydrogen atom, halogen atom, hydroxy group, alkyl group, alkoxy group, allyl group, etc. The electrophotographic sensitive body for copying machines and printers having the high sensitivity and excellent repetitive characteristics is obtd. by using said specific pyrazoline compd. as an electric charge transferable material. |
