    摘要: A process for the preparation of toner comprising mixing a colorant dispersion in water, which dispersion is comprised of a colorant and an ionic surfactant with a resin latex; heating the resulting flocculent mixture with stirring at a temperature of from about 25.degree. C. to about 1.degree. C. below the glass transition temperature (Tg) of the latex resin to effect formation of toner sized aggregates; heating the resulting aggregate suspension in the presence of additional anionic surfactant, and which heating is at a temperature of from about 10.degree. C. to about 55.degree. C. above the Tg of the resin; cooling; adding a base component to the resulting slurry; filtering; and thereafter drying said toner.
