Abstract
Disclosed herein is a photoreceptor for electrophotography comprising a conductive substrate and a photosensitive layer thereon containing an azo compound represented by the formula (I): A-N=N-D-N=N-B (I) wherein A represents a coupling component derived from the following formula (II): ##STR1## wherein Q represents a divalent group derived from an aromatic hydrocarbon which may have one or more substituents or a divalent group derived from a heterocyclic compound which may have one or more substituents, B represents a different coupling component having a phenolic hydroxyl group from said A, and D represents a divalent group in which the carbon atoms bonded to the azo groups are SP.sup.2 carbon atoms forming double bonds.
