Abstract
There is disclosed the electrophotographic photoreceptor having a high sensitivity and a low residual potential as well as an excellent durability in repeated use. The photoreceptor comprises a photoreceptive layer containing the bisazo compound represented by the following Formula I: ##STR1## wherein R.sub.1 represents a hydrogen atom, a nitro group, a cyano group, an alkyl group, or an alkoxy group; Z represents the group of non-metal atoms necessary to form an aromatic hydrocarbon ring or an aromatic heterocyclic ring by condensation with benzene ring; and R.sub.2 to R.sub.6 each represent a hydrogen atom, a halogen atom, a cyano group, a nitro group, an alkyl group, and an alkoxy group.
