Abstract
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.
