PROBLEM TO BE SOLVED: To provide an image forming method capable of avoiding the fouling on the surface of a charging roller, the scratch of a photoreceptor and the damage on the charging roller and capable of obtaining a stable image through the durability. SOLUTION: The image forming method comprises a charging process, a latent image forming process, a contact developing process, a transfer process and a cleaning process, wherein a charging member is an elastic roller composed of a conductive support, at least an elastic layer formed on the outer circumference of the conductive support and a cover layer covering the elastic layer, composite particles made by coating host particles with conductive material different from a constituent main component of the host particles are included at least in the cover layer of the charging member and, when the bulk density of the composite particles is Hc and the bulk density of the conductive material included in the surface layer of toner carrier is Hd, the following relation is satisfied; 1.3 < Hc / Hd < 3.0.
