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.

Color toner for non-magnetic mono-component system for increasing printing quality and a method for preparing the same

The present invention relates to a magnetic mono-component toner composition with positive charge comprising i) a magnetic toner particle containing a charge control agent with positive charge; ii) a hydrophobic silica with negative charge; iii) a fluorinated organic fine powder; and iv) a metal oxide fine powder containing 20 to 80 wt % of tin oxide. The toner has an advantageous in the extended life of the drum, reduction of the background contamination, and improvement of long-term reliability, and thus can be used effectively for image forming apparatus.

The present invention relates to a non-magnetic monocomponent color toner composition and a method for preparing the same, and more particularly to a non-magnetic monocomponent color toner composition having a narrow charge distribution, good charging characteristics, good environmental independence, superior image characteristics, high transfer efficiency and long-term stability caused by significantly improved charge maintenance capability, and a method for preparing the same. The non-magnetic monocomponent color toner composition of the present invention is prepared by coating organic particles having an average particle size of 0.3 to 2.0 &#x3bc;m, organic particles having an average particle size of 0.05 to 0.25 &#x3bc;m, and silica on toner mother particles.

Method for preparing of non-magnetic monocomponent color toner having superior long term stability

The present invention relates to a non-magnetic mono-component toner comprising a toner mother particle, and a coating layer formed on the mother particle where the coating layer comprises fatty acid metal salt having average particle size of 0.05 to 3.0 &#x3bc;m, a first organic particle having average particle size of 0.3 to 2.0 &#x3bc;m, a second organic particle having average particle size of 0.05 to 0.25 &#x3bc;m, and silica having average particle size of 0.006 to 0.04 &#x3bc;m. The color toner has narrow charge distribution, high chargeability, a low environmental dependence, and excellent image quality, transfer efficiency, and long-term stability by significantly reducing the contamination of the charging elements.

Color toner having low contamination of charging elements

The present invention relates to a non-magnetic monocomponent color toner and a preparing method thereof. In the non-magnetic monocomponent color toner including a toner mother particle, silica and titanium dioxide, the toner mother particle comprises a specific shaped particle size distribution of the charge control agents, and thus, providing non-magnetic monocomponent color toner with a narrow charge distribution and good chargeability. Accordingly, the color toner does not cause contamination in the non-imaging region. Also, because it has superior image density and printing efficiency and significantly improved charge maintenance, it has good long-term stability.
