PROBLEM TO BE SOLVED: To provide an image forming method capable of supporting a long service life, a high image quality and a low running cost, by maintaining a stable cleaning performance over a prolonged period without causing an image deletion phenomenon on a photoreceptor of high durability (high strength and high abrasion resistance). SOLUTION: The invention provides an image forming method for an image bearing member having a universal surface hardness HU (N/mm<SP>2</SP>) of 150 to 220 and an elastic deformation ratio We (%) of 40 to 65, and for a crossing angleθ(°) between the rotary axes of, respectively, the contact charging roller and the image bearing member, for a ratio A (mass%) of transfer residual toner to abrasive particles and for a contact pressure B (g/cm) of a cleaning blade, parameters HU, We, A, B andθsatisfying the following number relations (I), (II) and (III): (1/6000)×HU×We≤A×B, A/B≤θ, and 10≤B≤50.
