An organic photoconductive material is represented by the following general formula [1]: A1-N=N-B-N=N-A2 [1], wherein B is a divalent organic group bonded to nitrogen atoms forming azo groups, A1 and A2 are groups different from each other, A1 is represented by the following general formula [A1]: (see 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 A2 is a group represented by one of the following general formulae [A2] and [A3]: (see formula A2, A3) wherein a1 is a group selected from R, -N=CH-R and (see formula A4), 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.
