发明名称 Process for producing toner through suspension polymerization.
摘要 A process for producing a toner for developing an electrostatic image, including the steps of: adding to an aqueous dispersion medium a polymerizable monomer composition comprising at least a polymerizable monomer and a colorant uniformly dissolved or dispersed in the polymerizable monomer, wherein the aqueous dispersion medium containing as a dispersion stabilizer a hardly water-soluble metal hydroxide colloid formed by a reaction of a water-soluble polyvalent metal salt with an alkali metal hydroxide in an aqueous phase; and subjecting the polymerizable monomer composition to suspension polymerization, thereby to produce particles having a volume-average particle size in the range of from 2 to 20 mu m and a particle size distribution (a ratio of volume-average particle size/number-average particle size) of not more than 1.6.
