Abstract
A novel electrophotographic photoreceptor is provided comprising on an electrically conductive support a layer containing a charge carrier-transporting compound and a charge carrier-generating compound or a charge carrier-transporting compound-containing layer and a charge-generating compound-containing layer, characterized in that as said charge carrier-generating compound there is contained a novel bisazo compound represented by the general formula (1-A), (1-B) or (1-C): EQU Cp--N.dbd.N--Ar.sup.1 --C.tbd.C--.sub.n Ar.sup.2 --N.dbd.N--Cp (1-A) wherein Ar.sup.1 and Ar.sup.2 each represents an arylene group, divalent condensed polycyclic aromatic group or divalent heterocyclic aromatic group; Cp represents a coupler residue; and n represents an integer 2 or 3; EQU Cp--N.dbd.N--Ar.sup.1 --C.tbd.C--Ar.sup.2 --C.tbd.C--Ar.sup.3 --C.tbd.C--Ar.sup.4 --N.dbd.N--Cp (1-B) wherein Ar.sup.1, Ar.sup.2, Ar.sup.3 and Ar.sup.4 each represents an arylene group, divalent condensed polycyclic aromatic group or divalent heterocyclic aromatic group; and Cp represents a coupler residue; ##STR1## wherein Ar.sup.1, Ar.sup.2, and Ar.sup.3 each represents an arylene group, divalent condensed polycyclic aro…
