METHOD OF PREPARING TONER HAVING CORE-SHELL STRUCTURE AND TONER PREPARED USING THE SAME

摘要

Provided are a method of preparing a toner having a core-shell structure and a toner prepared using the method. The method includes: preparing a mixture by mixing a resin with acid groups, a coloring agent and at least one additive with an organic solvent, and neutralizing the acid groups of the resin with a base; forming a micro-suspension solution by adding the mixture to a dispersion medium; forming a toner core by removing the organic solvent from the micro-suspension; and forming a toner complex having a core-shell structure by seed-polymerizing at least one monomer on the surface of the toner core. Thus, the toner that can prevent hot offsets, improve storage stability at a high temperature and improve charge stability against environment changes can be prepared with reduced costs according to the method. In addition, the toner can be applied to an electrophotographic image forming device.
