Abstract:
1. An electrostatic photographic image forming method comprising: a latent image corresponding to a first color image on a photoreceptor by a developer containing a toner having a first color to form the first image color; developing a latent image corresponding to a second color image on the photoreceptor having the first color image by a developer containing a toner having a second color to form the second color image; transferring the piled color images formed on the photoreceptor; and fixing the transferred piled color images, wherein the toner having the first color comprises first toner particles and the toner having the second color comprises second toner particles, and each of the first and second toner particles has a variation coefficient of the shape coefficient of not more than 16% and the number variation coefficient in the number particle diameter distribution of not more than 27%.
