Mixture of titanyltetraazaporphyrin compounds and electrophotographic photoconductor using the same

摘要

A mixture is made of a plurality of different titanyltetraazaporphyrin compounds, each of which is represented by formula (1): chemistry chemdraw filechemistry mol file;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 a carbon atoms, and an aryl group. The above-mentioned mixture is contained in a photoconductive layer of an electrophotographic photoconductor as a photoconductive material.
