<p>PURPOSE:To attain sufficient releasing effect with a small quantity of a releas ing agent fixed, to increase flowability and transfer property and to obtain a bright image by fixing releasing agent fine particles containing a fluorine based 'Nonion(R)' surfactant on the surface of thermoplastic resin particles containing a colorant. CONSTITUTION:This toner is made by fixing the releasing agent particles containing the fluorine based 'Nonion(R)' surfactant on the surface of the thermoplastic resin particles containing the colorant. The producing method is composed of a process for producing the thermoplastic resin particles containing the colorant and a process for sticking and fixing the releasing agent particles containing the fluorine based surfactant. In this case, the particles made by coloring the resin particles obtained by dispersion polymerization is preferable as the colored resin fine particles because the particles having narrow particle diameter distribution and small particle diameter are easily obtained. Where, the dispersion polymerization is a method for polymerizing a monomer in a solvent, in which the monomers is dissolved but the polymer is not dissolved, in the presence of a dispersion stabilizer dissolved in the solvent.</p> |
