MANUFACTURING METHOD OF A TONER CAPABLE OF CONDUCTING A FUSION PROCESS AT LOW TEMPERATURE FOR SHORT TIME

摘要

PURPOSE: A manufacturing method of a toner is provided to easily and effectively manufacture toner particle with a precisely and moderately controlled average circularity.;CONSTITUTION: A manufacturing method of a toner comprises a step of obtaining a mixed dispersion by mixing acid polar group-containing resin particle-dispersed aqueous dispersion and colorant particle-dispersed aqueous dispersion; a step of adding di- or more valence metal ion-containing coagulant into the mixed dispersion and cohering the resin particle and colorant particle to form coagulated particle; and a step of adding a chelating agent into the dispersion and adding monovalent aqueous metal salt, and heating the same to fuse the resin particle and colorant particle in the coagulated particle.;COPYRIGHT KIPO 2013
