The invention is 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 an image bearing member (2) such as a photosensitive member of high durability (high strength and high abrasion resistance). The invention provides an image forming method for an image bearing member having a universal surface hardness HU (N/mm 2 ) of 150 to 220 and an elastic deformation ratio We (%) of 40 to 65, and for a crossing angle ¸(°) between the rotary axes of, respectively, the contact charging roller (2) and the image bearing member when pressed against each other, for a ratio A (weight %) of transfer residual toner to abrasive particles and for a contact pressure B (g/cm) of the cleaning blade, the parameters HU, We, A, B and ¸ satisfying the following number relations (I), (II) and (III): ( 1 / 6000 ) × HU × We ‰¤ A × B A / B ‰¤ ¸ 10 ‰¤ B ‰¤ 50 |
