Patent ID: 8263297

Claim:
An electrophotographic photoconductor comprising: a conductive support, and a photosensitive layer formed over the conductive support, wherein the photosensitive layer comprises a charge generation agent, a charge transport agent and a binder resin, and wherein the charge generation agent comprises an asymmetric disazo pigment represented by the following General Formula (I), the charge transport agent comprises a triphenylamine compound represented by the following General Formula (IX), and the ratio by mass of the charge transport agent to the binder resin is 0.3 to 2.0, where R 1 and R 2 each represent a substituted or unsubstituted alkyl group, alkoxy group, aryl group or heterocyclic group, provided that R 1 and R 2 are different, where R 3 to R 5 each represent hydrogen, a halogen atom, an alkyl group having 1 to 6 carbon atoms, which may have a substituent, an alkoxy group having 1 to 6 carbon atoms, which may have a substituent, or a substituted or unsubstituted aryl group having 6 to 12 carbon atoms.
