PROBLEM TO BE SOLVED: To provide a conductive member which has such a layer thickness of a surface coating layer as to arbitrarily control the appropriate surface roughness satisfying toner conveyability and toner electrostatic chargeability and the average spacing of ruggedness and has the sufficient film thickness of the surface coating layer as not to give rise to the occurrence of the contamination of a photoreceptor surface and further prevents the occurrence of toner filming arising between itself and a developing blade due to the falling impact during physical distribution. SOLUTION: The conductive member is formed of a conductive support, and at least one layer of an elastic layer and at least one or more of coating layers formed successively in this order on the outer periphery thereof, wherein the surface of the elastic layer is subjected to a surface treatment by irradiating the surface with the UV rays before the coating layer is formed on the elastic layer, and the outermost layer is coated with a resin and a coating layer material; the outermost layer has insulative particulates of 3 to 30μm in average grain size and conductive particulates of≤0.1μm in average grain size; and the relation between the average grain size (A)μm of the insulative particulates and the film thickness (B) of the portion where the insulative particulates of the outermost layer of the coating layer don't exist is A/B≤1.
