This invention relates to an electrophotographic photosensitive member having a support and a photosensitive layer.
In the electrophotographic photosensitive member having a support and a photosensitive layer, which electrophotographic photosensitive member makes use of, as writing light, a semiconductor laser light ray having a wavelength of from 380 to 500 nm, the photosensitive layer contains a bisazo pigment represented by the following Formula (1):
wherein A1, A2 and A3 may be the same or different, and each independently represent a saturated or unsaturated aliphatic hydrocarbon group which may have a substituent, an aromatic hydrocarbon ring group which may have a substituent, a heterocyclic ring group which may have a substituent, or a carbonyl group; R1 and R2 may be the same or different, and each independently represent an alkyl.group which may have a substituent, an aryl group which may have a substituent, or a halogen atom; R3, R4, R5 and R6 may be the same or different, and each independently represent a hydrogen atom, an alkyl group which may have a substituent, an aryl group which may have a substituent, a heterocyclic ring group which may have a substituent, or an aralkyl group which may have a substituent, provided that R3 and R4, and R5 and R6, may each form a cyclic amino group via the nitrogen atom in the formula; Z1 and Z2 each independently represent an oxygen atom or a sulfur atom; m1 and m2 each represent an integer of 0 to 4; and n1, n2 and n3 each independently represent. 0 or 1.
