Abstract
A preferred aspect of an electrophotographic photoconductor of the present invention contains a layer containing a hardened material which is prepared by polymerizing (A) a chain-polymerizable group-containing tertiary amine compound in which at least one alkyl group is bound to a nitrogen atom constituting an amine structure through chain polymerization. Another preferred aspect of the electrophotographic photoconductor contains a layer containing a hardened material which is prepared by polymerizing the (A) component, and (B) a chain-polymerizable charge transporting compound through chain polymerization. Still another preferred aspect of the electrophotographic photoconductor contains a layer containing a hardened material which is prepared by polymerizing the (A) component, (B) the chain-polymerizable charge transporting compound, and (C) a trifunctional or more chain-polymerizable compound through chain polymerization.
