METHOD FOR MANUFACTURING ELECTROPHOTOGRAPHIC TONER

摘要

PROBLEM TO BE SOLVED: To provide a method for an electrophotographic toner which is excellent in fog characteristics by preventing aggregation of pulverized particles to improve classification yield in a production process. SOLUTION: The method includes steps of: mixing a source material containing a binder resin and a colorant; melting and kneading the source material mixture; cooling and solidifying the kneaded material and then coarsely pulverizing the material; mixing water of 1 to 10 parts by mass or an alkaline electrolytic water of 0.5 to 10 parts by mass based on 100 parts by mass of the coarse pulverized product; pulverizing the mixture; and classifying the pulverized material.
