摘要： An electrophotographic image forming method is disclosed. The method comprises developing latent images each formed on a static latent image forming member by serially arranged plural image forming units each including a toner to form toner images, respectively, successively transferring the toner images onto an image support so as to form a piled up image, and fixing the piled up image by a fixing device having a rotatable heating member including a heater fixed therein and a pressing member, and in the method the toner for developing the latent image has a variation coefficient of the shape coefficient of not more than 16% and a number variation coefficient of the particle diameter distribution in number of not more than 27%.
