    Abstract: Hydrazone compounds having the general formula ##STR1## wherein Ar is selected from the group consisting of a naphthalene ring radical, substituted naphthalene ring radicals, an anthracene ring radical, substituted anthracene ring radicals, styryl, substituted styryls, a pyridine radical, a furan ring radical and a thiophene ring radical.The hydrazone compounds can be prepared by allowing 1-methyl-1-phenylhydrazine having the formula ##STR2## to react with an aldehyde represented by the general formula Ar-CHO, wherein Ar is the same as mentioned above at a substantially equal molar ratio in an organic solvent selected from the group consisting of lower alcohols, cyclic ethers, cellosolves, N,N-dimethylforamide and acetic acid, in the presence of an acid catalyst, by heating and refluxing the reaction mixture.The hydrazone compounds are extremely useful as charge transport materials for use in electrophotographic photoconductors of the type comprising an electroconductive support material and a photosensitive layer containing a charge generation material and a charge transport material.
