Document Type and Number:
Japanese Patent JP4181603
Kind Code:
B2
Abstract:
A toner includes aggregated particles produced by preparing in an aqueous medium a mixed dispersion including at least a first resin particle dispersion in which first resin particles are dispersed, a colorant particle dispersion in which colorant particles are dispersed, and a wax particle dispersion in which wax particles are dispersed, heating the mixed dispersion so that at least part of the wax particles is melted, and aggregating the first resin particles, the colorant particles, and the wax particles at least part of which is melted by the addition of an aqueous solution containing an aggregating agent. Thus, the toner can have a smaller particle size and a sharp particle size distribution without requiring a classification process. Moreover, the toner can achieve a longer life and suppress transfer voids or scattering during transfer.
