Abstract: With the requirement for high quality printing，the market demand for high quality color toner will also increase. The preparation methods of the laser color toner were reviewed in this article，and emulsion polymerization and suspension polymerization methods and their research progress for preparing color toner were highlighted，the future technology and methods for toner producing were prospected. The authors believed that the color toner produced by emulsion polymerization can provide higher resolution，higher color saturation and suitable consolidation property；it will replace those produced by suspension polymerization and become a lead in the future market of color toner.

Key words: color toner, electrostatic develop, emulsion polymerization method
