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.

摘要:
In an image forming apparatus that employs a system of charging by adjacent discharge, not only can degradation of the photoreceptor surface caused by adjacent discharge be prevented, but also there is no side effect on the developer, and at the same time size reduction is achieved. The image forming apparatus comprises an object to be charged whose surface moves; a charging device for charging the object to be charged using an electrical discharge generated by applying a voltage comprising an alternating current component to a charging member provided in contact with or in proximity to the object to be charged; a latent image forming device for forming an electrostatic latent image on the surface of the object charged by the charging device; and a developing device for causing a two-component developer to come into contact with the image portion of the electrostatic latent image formed by the latent image forming device and affixing toner thereto. A protective substance is present on the surface of the object to be charged in the discharge region for charging the object to be charged, and the saturation magnetization of the carrier of the two-component developer with respect to an applied magnetic field of 1000 oersted is 40 to 80 emu/g.
