<p>PROBLEM TO BE SOLVED: To obtain a color image forming material high in color density, and a color toner for developing an electrostatic charge image and useful for obtaining this color image forming material, by incorporating an inorganic pigment, a glass component, and a thermoplastic resin, and specifying the grain diameter. SOLUTION: The color toner contains the inorganic pigment, the glass components, and the thermoplastic resin and it is regulated to have the grain diameter range of 20-60μm. As the metal oxide, such as Indian red, chrome green and the like, and as the solid solution of the metal oxide, such as mangan pink or chrome alumina green, and as double oxides, (Zn, Co)OAl2 O3 and the like, and as the solid solution of the composite, such as antimony yellow, are enumerated. As the glass components, the hydroxide of alakali metals, or alkaline earth metals, such as lithium hydroxide and the like, and glasslets are enumerated as fundamental materials alone or in combination of them, and as the thermoplastic resin, polyesters and polystyrenes, such as a copolymer of polyester, copolymers, such as styrene and ethyl acrylate copolymers are enumerated.</p> |
