ABSTRACT:
An electrostatic image forming method is disclosed. The photoreceptor containing an organic photosensitive material has a layer containing fine particles at the photoreceptor surface; toner has at least binder resin, coloring agent, and releasing agent made of polyolefines in which the ratio, Mz/Mn, is is 3-20, and Mz is 20,000-70,000 wherein Mz is Z-average molecular weight in terms of polypropylene and Mn is the number average molecular weight in terms of polypropylene. No offset phenomenon occurs, and a stable image having no fogging and no black-spots can be formed for a long period of time by the invention.
