Method for manufacturing mixed color toner, involves determining zeta potential distribution of each of color toner

摘要

The method involves determining a zeta potential distribution of each of the color toner. The color toner is mixed in such a combination that the overlapping part of the zeta potential distribution ranges to 70 percent or more. Each of the color toner comprises a polyester as a resin binding agent. Independent claims are also included for the following: (1) a two component developer (2) a method for generation of fixed images.
