    摘要： A process for the preparation of toner comprising (i) solubilizing an imide based resin in water at pH of from about 10 to about 13 and which solubilizing is accomplished in the presence of nonionic surfactants and anionic surfactants; followed by precipitating the resulting dissolved imide resin into colloidal particles with a size diameter of from about 20 nanometers to about 500 nanometers, and which precipitating is accomplished with a high shearing device operating at a speed of from about 500 to about 2,000 revolutions per minute; acidifying the resulting mixture to a pH of from about 2 to about 4; (ii) preparing a pigment dispersion in water, which dispersion is comprised of a pigment, an oppositely charged ionic surfactant and optionally charge control agent; (iii) shearing (i) and (ii), thereby causing a flocculation of the resin, pigment, surfactants, and optional charge control agent; (iv) heating the resulting flocculent mixture of (iii) with stirring at a temperature of from about 25.degree. C. to about 1.degree. C. below the glass transition temperature (Tg) of the imide resin to effect formation of electrostatically bounded toner sized aggregates, and wherein the imide resin has a Tg of from about 45.degree. C. to about 65.degree. C.; (v) heating the resulting aggregate suspension of (iv) in the presence of additional anionic surfactant selected in an amount of from about 0.01 to about 5 weight percent based on the weight percent of the total reaction mixture solids, and which heating is at a temperature of from about 10.degree. C. to about 55.degree. C. above the Tg of the imide resin; and optionally cooling, and optionally (vi) separating said toner by washing, and thereafter drying said toner.
