Patent ID: 7320851

Claim:
A toner composition comprising toner particles formed by an emulsion aggregation process, wherein the emulsion aggregation process comprises: (i) providing one or more aqueous dispersions, the aqueous dispersions comprising particles including particles of one or more resins; (ii) mixing the aqueous dispersions in presence of a coagulant; (iii) adding one or more wax emulsions to the aqueous dispersions; (iv) aggregating to form aggregated particles; (v) adding one or more aqueous dispersions, which comprise particles including particles of one or more resins, to form toner size particles; (vi) coalescing the toner size particles to form fused particles; and (vii) removing the fused particles from the aqueous dispersion; wherein said adding one or more wax emulsions is performed after said mixing; the fused particles have an average particle diameter of from about 1 to about 15 microns, with a particle geometric size distribution of less than about 1.3; and wherein the waxes are excluded from an interior core of the toner particles.
