    摘要： An electrophotographic photosensitive member is formed of a support, and a photosensitive layer disposed on the support. The photosensitive layer is characterized by containing an azo pigment having an organic group represented by formula (1) below:
    wherein A denotes a residue group of formula (1A) below:
    and k 1 , k 2 , Z 1 , Z 2 , D; R 1 and R 2 are defined in the text. The group of the formula (1) may provide at least one of up to 4 azo-substituents of the azo pigment having an entire structure represented by

            Ar(̵N=N-Cp) 1-4 ,

    wherein Ar denotes an aromatic or heterocyclic core unit, Cp denotes a coupler residue group, and -(N=N-Cp) denotes such an azo-substituent. The photosensitive member can exhibit good electrophotographic performances including high and stable sensitivity on repetitive use.

    摘要： An electrophotographic photoreceptor is provided with a photosen­sitive layer, which contains an azo compound having in the molecule thereof at least one azo group coupled with a couple residuum represented by the following general formula (I):
    wherein X means an atomic group necessary for condensing with a benzene ring to form a substituted or unsubstituted aromatic hydrocarbon ring, or substituted or unsubstituted aromatic heterocyclic ring, Y denotes a radical selected from the group consisting of hydrogen, halogen atoms, cyano radicals, and substituted or unsubstituted alkyl, or alkoxy group, and n stands for an integer of 0∼4, R₁ and R₂ designate, respectively, hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted alalkyl, substituted or unsubstituted aromatic hydrocarbon ring or substituted or unsubstituted aromatic heterocyclic ring, and said R₁ and R₂ may be mutually same or different, or may form a ring together with nitrogen atom.
