摘要： An electrophotographic photosensitive member comprising an electroconductive support and a photosensitive layer on said electroconductive support, said photosensitive layer containing
a compound represented by the formula (4)
wherein R 4-1 is a thiophene ring group having a nitro group; each of R 4-2 and R 4-3 is a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aromatic ring group, a nitro group, a cyano group, -(CH=CH) f -NO 2 , -(CH=CH) g -R 4-4 or
and at least either of R 4-2 and R 4-3 is -(CH=CH) f -NO 2 , -(CH=CH) g -R 4-4 or
each of R 4-4 and R 4-5 is an aromatic ring group having a nitro group or a heterocyclic ring group having a nitro group; and R 4-6 is a substituted or unsubstituted alkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aromatic ring group, or a substituted or unsubstituted heterocyclic ring group; and each of f and g is an integer of 1 or 2; h is an integer of 0 or 1; each of R 4-5 and R 4-6 may be bonded to form a ring directly or with the interposition of a saturated hydrocarbon, an unsaturated hydrocarbon, an oxygen atom or a sulfur atom.
