TONER PARTICLES AND METHODS OF PREPARING THE SAME

摘要

Toner particles comprise resin, wax and optionally colorants, and the wax is substantially excluded from the interior core of the toner particles. Processes for preparing such toner particles comprise providing an aqueous dispersion of resin particles and optionally colorants, mixing the aqueous dispersion in presenc e of a coagulant, aggregating to form particles, coalescing to form fused particles , and removing the fused particles from the aqueous dispersion. Wax dispersions ca n be added either after mixing or during aggregation, so that wax is excluded fro m the core of the toner particles.
