Patent ID: 6849367

Claim:
An electrophotographic photoconductor comprising: a conductive support; and a photoconductive layer disposed on the photoconductive support; wherein the photoconductive layer contains an azo compound expressed by a general formula <<1>>: ArN═N—Cp) n general formula <<1>> wherein in the general formula <<1>>, Ar expresses one of a substituted or non-substituted aromatic hydrocarbon group and heterocyclic ring aromatic series group which can be combined by way of a bonding group; Cp expresses a coupler residual group; n expresses an integer of one of 1, 2, 3, and 4; at least one of the Cp is a coupler residual group selected from one of the following general formulae <<2>>, <<3>>, and <<4>>: wherein in the general formulae <<2>>, <<3>>, and <<4>>, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 each expresses one of a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom, an amino group, a hydroxy group, a nitro group, and a cyano group; X represents one of a hydrogen atom, a substituted or non-substituted alkyl group, a substituted or non-substituted aromatic series hydrocarbon group, a substituted or non-substituted heterocyclic ring group, and a substituted or non-substituted amino group; and Y represents one of a substituted or non-substituted alkylene group, a substituted or non-substituted aromatic series divalent organic residual group, a substituted or non-substituted heterocyclic ring aromatic series divalent organic residual group, and a —CO—Z— carbonyl group containing divalent organic residual group, in which Z represents one of a substituted or non-substituted alkylene group, a substituted or non-substituted aromatic series divalent organic residual group, and a substituted or non-substituted heterocyclic ring aromatic series divalent organic residual group.
