    摘要： An object is to provide an electrophotographic photoconductor which prevents an increase in the friction coefficient of the photoconductor surface caused when printing takes place for a long period of time or in large amounts, which has sustainability of the low photoconductor surface friction coefficient, low wear properties and high durability, and which is particularly superior in polymerized toner (or spherical toner) cleaning capability; a process cartridge incorporating the electrophotographic photoconductor; and an image forming apparatus incorporating the electrophotographic photoconductor. There is an electrophotographic photoconductor including: a photoconductor substrate, a photosensitive layer over the photoconductor substrate, and a protective layer over the photoconductor substrate, wherein the protective layer is formed by curing together at least a trifunctional or more radical polymerizable monomer having no charge transporting structure, a fluorine-based UV-curable hard coat agent and a monofunctional radical polymerizable compound having a charge transporting structure, and contains lubricant fine particles.
