摘要： An electrophotographic image-forming method is disclosed. The image forming method comprises the steps of (1) forming an electrostatic latent image on a rotating electrophotographic photoreceptor having an organic photoconductive layer, (2) developing the electrostatic latent image with a toner comprising toner particles which contain a releasing agent existing in the toner particle in a form of insular domain having a number average diameter of 0.1 .mu.m to 1.1 .mu.m to form a toner image, (3) transferring the toner image to an image receiving member, and (4) cleaning the surface of the photoreceptor after the transferring step by a cleaning member having a rubber elastic cleaning blade having an impact resilience of 35 to 75% which is contacted to the surface of the photoreceptor in the direction counter to the rotating direction of the photoreceptor with a pressure of 5 to 40 g/cm, and the coefficient of static friction between the cleaning blade and the surface of the photoreceptor is not more than 1.0.
