Synthesized superior toner with intension of protection of environment is developed aiming energy saving and environment lord decreasing. The new polymerization toner is synthesized with new manufacturing method that utilized ester elongate reaction of a pre-polymer. The new polymerization toner is superior to usual polymerization toners in low temperature fixing. It consists of polyester resins, while usual toners consist of styrene-acrylic copolymers. The futures of new polymerization toner are as follows; (1) Energy saving by low temperature fixing with polyester resins. (2) High image quality and reduction of 40% in toner consumption ( the antecedent machine ratio) by super fine toner. (3) Superior characteristics in toner cleaning process. (4) Reduction of 35% in environmental load (as CO_2 discharge).
