To provide a latent electrostatic image bearing member including: an outermost surface layer that comprises a compound represented by the following General Formula (1) and a crosslinked resin formed by crosslinking between an isocyanate compound and a reactive charge transporting substance having at least two hydroxyl groups. where Rand Rmay be identical or different and each represent a substituted or unsubstituted alkyl group; and Rrepresents one of alkyl and aryl groups which have at least one hydroxyl group.

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.
