    摘要： A mixture is made of a plurality of different titanyltetraazaporphyrin compounds, each of which is represented by formula (1): wherein A, B, C and D are each independently an unsubstituted or substituted benzene ring or pyridine ring, a substituent thereof being selected from the group consisting of nitro group, cyano group, a halogen atom, an alkyl group having 1 to 8 carbon atoms, an alkoxyl group having 1 to 8 carbon atoms, and an aryl group. The above-mentioned mixture is contained in a photoconductive layer of an electrophotographic photoconductor as a photoconductive material.
