    摘要: A method of preparing a toner having a core-shell structure. 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.
