摘要： An electrophotographic photoreceptor is provided with a photosensitive layer, which contains an azo compound represented by the followin g general formula (1):

wherein A means a coupler residuum having phenolic OH radicals, R₁ and R₂ designate, respectively, a radical of an integer of, both, m=0∼4, n =0∼4, selected from the group consisting of hydrogen, halogen atoms, alkyl group, alkoxy group, and di-substituted amino group.
The electrophotographic photoreceptor of this invention has excellent electrification characteristics, sensitivity characteristics and image-forming property as well as good sensitivity. In addition, its sensitivity and electrification characteristics undergo less variations even when employed repeatedly. It also undergoes little light-induced fatigue. It has high weatherability.

摘要： An organic photoconductive material is represented by the following general formula [1 ]:
wherein B is a divalent organic group bonded to nitrogen atoms forming azo groups, A 1 and A 2 are groups different from each other, A 1 is represented by the following general formula [A1 ]:
wherein X is an atomic group which is necessary for forming an aromatic hydrocarbon ring or an aromatic hetero-ring by condensation with the benzene ring, Y is a hydrogen atom, an alkyl group, an alkoxy group or a halogen atom, m is an integer of 1 to 4, R is an aromatic hydrocarbon ring group or an aromatic hetero-ring group and n is 1 or 2, and A 2 is a group represented by one of the following general formulae [A2] and [A3]:
wherein a 1 is a group selected from R, -N = CH-R and
R, X, Y, m and n are the same as those in the general formula [A1 ] and p is 0 or 1. A photosensitive material for electronic photography having excellent properties, such as charging property, retention of charge, sensitivity, residual voltage and image formation, and showing no change of the properties after repeated use for a long time can be obtained by using an azo compound having a specific structure as the carrier generating substance. A photosensitive material for electric photography of a laminate type or a dispersion type having high performance and high durability can also be provided.
