ABSTRACT:
The invention is to provide an image forming method of a long service life, a high image quality and a low running cost, capable of maintaining a stable cleaning performance over a prolonged period without causing an image deletion phenomenon, even with a image bearing member such as a photosensitive member, of a high durability (high strength and high abrasion resistance). The invention provides an image forming method characterized in that the image bearing member has a universal surface hardness HU of 150 to 220 N/mm2and an elastic deformation ratio We of 40 to 65%, and, for a crossing angle θ (°) between a rotary axis of the contact charging roller and a rotary axis of the image bearing member, for a ratio A (weight %) of the transfer residual toner and the abrasive particles and for a contact pressure B (g/cm) of the cleaning blade, HU, We, A, B and θ satisfy the following relations (I), (II) and (III):in-line-formulae description="In-line Formulae" end="lead"?(1/6000)×HU×We≦A×B  (I)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?A/B≦θ  (II)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?10≦B≦50.   (III)in-line-formulae description="In-line Formulae" end="tail"?
