PURPOSE:To obtain a photoconductive film having high sensitivity by incorporating a specific hexaazo compd. therein. CONSTITUTION:At least one kind of the hexaazo compd. expressed by the formula I is incorporated into the above-mentioned film. In the formula I, A denotes the formula II, etc.; R1, R2 denote a hydrogen atom, lower alkyl group, etc.; Z denotes a substd. or unsubstd. methylene group, substd. or unsubstd. imino group, etc.; Ar1-Ar4 respectively denote a substd. or unsubstd. hydrocarbon or hetero system arom. cyclic group or bivalent residual org. group. In the formula II, R denotes a hydrogen atom, lower alkyl group, etc. The photoconductive film having the high sensitivity and the electrophotographic sensitive body formed by using said film are thereby obtd. |
