ABSTRACT:
An electrophotographic image forming method is disclosed. The method contains steps of forming an electrostatic latent image on an organic photoreceptor, and developing the electrostatic latent image by a developer containing toner to form a toner image on the photoreceptor. In this method the photoreceptor contains inorganic particles in a surface layer, the toner has circle equivalent diameter d of 3.0 to 8.0 μm viewed from a direction which maximizes the projective area of toner particles, the toner has a flatness ratio d/t of 2.0 to 5.0, wherein d is circle equivalent diameter and t is average thickness of toner particles, and the electrostatic latent image is developed in such a manner that the developing sleeve is rotated in the opposite direction to the photoreceptor.
