Abstract

The present invention relates to a color toner for a nonmagnetic mono-component printing system that improves the printing characteristics, and a preparation method thereof. More specifically, the present invention provides a color toner including a first coating layer and a second coating layer formed on a toner mother particle, wherein the first coating layer contains coated organic powders where two kinds of organic powders are coated with each other, and the second coating layer contains coated inorganic powders where silica and titanium dioxide are coated with each other. The color toner of the present invention has a narrow charge distribution, good image density, high transfer efficiency, excellent long-term stability, and reduced PCR contamination, thereby being good for use in high speed color printers, etc., employing a direct type or a tandem type of transfer system.
