Provided are a toner containing a resin having wax properties and a method of preparing the toner. The toner includes a binder resin into which at least one residue of the group consisting of a C8-C60 higher fatty acid residue and a C8-C60 higher alcohol residue is introduced by esterification, a colorant, and at least one additive.
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.

摘要:
A method of preparing a toner using a micro-suspension particle, includes preparing a mixture by mixing a resin having acidic groups, a master batch of coloring pigment, and at least one additive with an organic solvent, and then neutralizing the acid groups of the resin with a base; forming a micro-suspension by adding the prepared mixture to a dispersion medium; and forming a toner composition by removing the organic solvent from the prepared micro-suspension. Therefore, the method of preparing a toner using the disclosed micro-suspension particle and a toner prepared using the same can save manufacturing costs, and can improve charging ability and cleaning properties of the toner.
