<p>PROBLEM TO BE SOLVED: To provide a combination of toners which makes the formation of colors varying in a wide range of color gamut possible and have excellent color resolution of high lightness and triboelectric characteristics. SOLUTION: This combination is a combination of the four color toners for developing electrostatic latent images capable of forming the images of the entire color gamut. These four toners are composed of a cyan toner, magenta toner, yellow toner and black toner. The respective toners consist of resins and pigments. The pigment for the cyan toner isβcopper phthalocyanine, the pigment for the magenta toner is monoazolitholrubin, the pigment for the yellow toner is isoindoline and the pigment for the black toner is carbon black.</p> |
