    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: ##STR1## wherein X.sub.1, Z.sub.1, k.sub.1, B, A, R.sub.1 and R.sub.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 byAr.paren open-st.N.dbd.N--Cp) 1-4,wherein Ar denotes an aromatic or heterocyclic core unit, Cp denotes a coupler residue group, and --(N.dbd.N--Cp) denotes such an azo-substituent. The photosensitive member can exhibit good electro-photographic performances including high and stable sensitivity on repetitive use.

    摘要: A disazo compound is provided which is represented by the formula (I): ##STR1## (wherein, R.sub.1 and R.sub.2 each stands for hydrogen, a lower alkyl group with 1-4 carbon atoms, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aromatic group, or a substituted or unsubstituted hetero ring group. R.sub.1 and R.sub.2 may be the same or different. And, R.sub.1 and R.sub.2 may mutually bond to form a ring).This disazo compound may be obtained by diazotating 2.6-diaminoanthraquinone and reacting the same with a coupler represented by the formula (IV): ##STR2## (wherein, R.sub.1 and R.sub.2 are the same as defined above). Further, a multilayer type electrophotographic element is provided which comprises a charge carrier generating layer and a charge transfer layer and uses, as a charge carrier generating substance, a disazo compound represented by the formula (I).
