摘要

An electrophotographic photoconductor includes a conductive support; and a photoconductive layer that contains at least a charge generation material, a hole transport material, an electron transport material and a binder resin, and that is provided on the conductive support, wherein the photoconductive layer has an outermost layer that contains a charge generation material, a hole transport material, an electron transport material, a binder resin and a highly branched polymer that is obtained by polymerizing, in the presence of a polymerization initiator, a monomer having, in a molecule, two or more radically polymerizable double bonds and a monomer having, in a molecule, a long-chain alkyl group or an alicyclic group and at least one radically polymerizable double bond. The electrophotographic photoconductor exhibits superior operational stability and stably high image quality, without problems with image memory, a contact member, or image defects due to cracks caused by contamination by oils/fats or sebum.
