<p>PURPOSE:To provide the electrostatic charge image developing toner with which bright images are obtainable at a high density and which has excellent flowability offset resistance, release property, fixability and durability by fixing release agent particulates coated and/or impregnated with a thermoplastic resin to the surfaces of coloring resin particles. CONSTITUTION:The release agent particulates coated and/or impregnated with the thermoplastic resin are fixed to the surfaces of the coloring resin particles. The Tg of the thermoplastic resin of the release agent particulates coated and/or impregnated with the thermoplastic resin is specified to 60 to 100 deg.C. The thermoplastic resin of the release agent particulates is formed of a polymer or copolymer of fluoroalkyl methacrylate. The coloring agent particles to be used are preferably the particles formed by coloring the resin particles obtainable by a dispersion polymn. method as the particles of small grain sizes of a narrow grain size distribution are obtainable. These resin particles are preferably colored with dyes in terms of fixability.</p> |
