PURPOSE:To improve the oxidation resistance of an electrostatic charge transferring material which transfers positive holes by using a novel benzidine compound as the charge transferring material. CONSTITUTION:A benzidine compound represented by formula I is used as a charge transferring material which transfers positive holes in an electrophotographic sensitive body or the like. The compound is obtd. by reacting a dihalobiphenyl deriv. represented by formula II with a diarylamine represented by formula III. In the formulae I-III, R1 is alkyl, alkoxy or halogen, each of R2 and R3 is H, alkyl, alkoxy, halogen, alkoxy-carbonyl or substituted amino and X is halogen. When the novel benzidine compound is used as the charge transferring material, the oxidation resistance of the charge transferring material can be improved. |
