<p>PURPOSE:To obtain a bright image by incorporating a 1st toner particle having a 1st average particle diameter and a toner having a smaller 2nd average particle diameter than the 1st average particle diameter to prevent the generation of filming of a photoreceptor and to truly make an electrostatic charge latent image visualizable. CONSTITUTION:The 1st toner particle containing a binder resin, a coloring agent and a wax of a 1st ratio to the binder resin and having the 1st average particle diameter and the toner particle containing the binder resin, the coloring agent and the wax of a 2nd ratio to the binder resin, which is smaller than the 1st ratio, and having the 2nd average particle diameter, which is smaller than the 1st average particle diameter, are incorporated. That is, the wax content in the toner particle having smaller particle diameter is reduced and the generation of filming on the photoreceptor is prevented by mixing at least two kinds of the toner setted so that the wax content in the toner particle having smaller particle diameter is less than that having the larger particle diameter.</p> |
