Electrophotographic photoreceptor.

摘要

An novel electrophotographic photoreceptor is provided comprising on an electrically conductive support a layer containing a charge-transporting compound and a charge-generating compound or a charge-transporting compound-containing layer and a charge-generating compound-containing layer, wherein said charge-generating compound is a trisazo compound represented by the general formula (1): <CHEM> wherein Ar<1>, Ar<2>, Ar<3>, Ar<4>, Ar<5> and Ar<6> each represents an arylene group, divalent condensed polycyclic aromatic group or divalent group derived from a monocyclic or condensed polycyclic heterocyclic aromatic group, each of which may have one or more substituents; Cp represents a coupler residual group; and n represents 1 or 2.
