Abstract
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 μm, a first organic particle having average particle size of 0.3 to 2.0 μm, a second organic particle having average particle size of 0.05 to 0.25 μm, and silica having average particle size of 0.006 to 0.04 μm. 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.
