Abstract
A process for preparing a mixed color toner obtained by mixing two or more kinds of color toners of which each color is different, including the following steps (1) and (2): (1) determining zeta potential distributions of each of the color toners, and (2) mixing the color toners in combination so that an overlapping ratio of the zeta potential distributions is 70.0% or more; a mixed color toner obtainable by the process; a two-component developer containing the toner; and a method of forming fixed images using the toner. The mixed color toner obtainable by the present invention is used for, for example, developing a latent image formed in electrophotography, electrostatic recording method, electrostatic printing method, or the like.
