Patent ID: 7056633

Claim:
An electrophotographic photoconductor comprising: an electroconductive support and a photoconductive layer which is formed on said electroconductive support and comprises a charge generation layer comprising a charge generation material and a charge transport layer comprising a first charge transport layer comprising a charge transport material and a second charge transport layer comprising a charge transport material and at least one polycarbonate resin wherein the resin comprises at least a structural unit represented by formula (1): wherein R 1 and R 2 are each a halogen atom, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted alkoxyl group having 1 to 6 carbon atoms, or a substituted or unsubstituted aryl group; R 3 is an alkyl group represented by —(CH 2 ) m CH 3 ; a and b are each an integer of 0 to 4, and when a and b are each an integer of 2 to 4, a plurality of groups represented by R 1 or R 2 may be the same or different; and n and m are each an integer of 8 to 27, wherein a contact angle which pure water makes with a surface of said photoconductive layer is in a range of 85 to 140°; and wherein said charge generation layer and said charge transport layer being successively overlaid on said electroconductive support in this order, and said first charge transport layer and said second charge transport layer being successively overlaid on said charge generation layer in this order.
