PURPOSE:To improve photosensitive characteristics and to enhance the strength to heat and impact by providing a photosensitive layer contg. an aminobiphenyl compd. expressed by prescribed formula as an effective component on a conductive base. CONSTITUTION:The photosensitive body 2 contg. at least one kind of the compd. expressed by formula I [R<1>, R<2>, R<3> denote a hydrogen atom, amino group, alkoxy group, thioalkoxy group, aryloxy group, methylenedioxy group, substd. or unsubstd. alkyl group, halogen atom or substd. or unsubstd. aryl group; R<2> denotes a hydrogen atom, alkoxy group, substd. or unsubstd. alkyl group or halogen group, exclusive of the case in which all of R<1>-R<4> are the hydrogen atom; (k), l, m, n denote 1, 2, 3 or 4 integer and R<1>-R<4> may be the same as or different from each other when if each thereof is 2, 3, 4 integer] as the effective component is provided on the conductive base 1. This photosensitive body 2 has the excellent photosensitive characteristics and the improved durabil ity. |
