More Information
Summary:A method for producing a toner having a core-shell structure is provided to improve the cost-efficiency, to prevent hot offset, and to impart improved heat resistance, shelf stability and electric charge stability to a toner. A method for producing a toner by using micro-suspension particles comprises the steps of: (a) mixing an acid group-containing resin, colored pigment master batch, release agent and at least one additive in an organic solvent and neutralizing the acid group with a base to provide a mixture; (b) adding the mixture to a dispersion medium to form a micro-suspension; (c) removing the organic solvent from the micro-suspension to form a toner core; (d) carrying out seed polymerization of at least one monomer on the surface of the toner core to form a toner composite having a core-shell structure; and (e) coagulating the toner composite.
