Patent ID: 7985519

Claim:
An electrophotographic photoreceptor comprising: a conductive substrate; and a photosensitive layer containing an aromatic polycarbonate on the conductive substrate, wherein the aromatic polycarbonate comprises a constituent unit represented by the following general formula (1): where Ar 1 and Ar 2 are identical with or different from each other and each represent an aryl group which may have a substituent or a heterocyclic group which may have a substituent, Ar 3 represents an arylene group which may have a substituent or a bivalent heterocyclic group which may have a substituent, two Ar 4 are identical with or different from each other and each represent an arylene group which may have a substituent or a bivalent heterocyclic group which may have a substituent two Ar 5 are identical with or different from each other and each represent a hydrogen atom, an aryl group which may have a substituent, a heterocyclic group which may have a substituent, an aralkyl group which may have a substituent, or an alkyl group which may have a substituent, Ar 6 represents an arylene group which may have a substituent or a bivalent heterocyclic group which may have a substituent, providing that Ar 3 and Ar 6 should not be identical, R 1 represents a hydrogen atom or an alky group which may have a substituent, R 2 and R 3 by the number of 2n are identical with or different from each other and each represent a hydrogen atom, an alkyl group which may have a substituent, an aryl group which may have a substituent, a heterocyclic group which may have a substituent, or an aralkyl group which may have a substituent, and n represents an integer of 0 to 2).
