ABSTRACT:
An electrophotographic image forming method is disclosed. In the method each of a plurality of toner images formed on the latent image bearing body is sequentially onto an intermediate transfer body, and the transferred image on the intermediate transfer body is transferred to an image forming support, and fixed using a heating roller fixing system, and the toner satisfies ratio (Dv50/Dp50) is from 1.00 to 1.15; ratio (Dv75/Dp75) is from 1.00 to 1.20; and the content ratio of toner having a particle diameter of at most 0.7×(Dp50) is less than or equal to 10 percent by number. Dv50, Dp50, Dv75 and Dp75 are specified in the specification.
