    摘要： The present invention provides an electrophotographic photoconductor which contains a substrate, at least a photosensitive layer and a surface layer being formed on the substrate in this order; the surface layer contains a cured material which is cured by irradiating with light a trifunctional or more radical polymerizable monomer having no electric charge transportable structure, a radical polymerizable monomer having an electric charge transportable structure, and a photo-radical polymerization initiator; the photo-radical polymerization initiator contains a titanocene derivative; and the relation between the absorption edge wavelength HA (nm) in the light absorption spectrum of the radical polymerization initiator and the absorption edge wavelength HB (nm) in the light absorption spectrum of the radical polymerizable monomer having an electric charge transportable structure is represented by HA>HB and satisfies HA−HB>40 nm.

    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.
