    摘要： A process for the preparation of toner comprising:(i) preparing a pigment dispersion comprised of pigment, an ionic surfactant, and optionally a charge control agent;(ii) shearing said pigment dispersion with a latex comprised of resin, a counterionic surfactant with a charge polarity of opposite sign to that of said ionic surfactant, and a nonionic surfactant;(iii) heating the above sheared blend of (ii) about below the glass transition temperature (Tg) of the resin, to form electrostatically bound toner size aggregates with a volume average diameter of from between about 2 and about 15 microns and with a narrow particle size distribution as reflected in the particle diameter GSD of between about 1.15 and about 1.30, followed by the addition of a water insoluble transition metal containing powder ionic surfactant in an amount of from between about 0.05 and about 5 weight percent based on the weight of the aggregates; and(iv) heating said bound aggregates about above the Tg of the resin to form toner.
