<p>PURPOSE: To manufacture a toner for developing an electrostatic charge image excellent in fluidity, offset resistance, mold releasability, transferability, fixability, and durability and capable of obtaining a high-density and clear image. CONSTITUTION: Mold releasing agent fine grains are fixed (preferably buried) to the surface of colored resin grains to form this toner for developing an electrostatic charge image. A vinyl polymer film obtained by emulsifying and polymerizing a vinyl monomer containing a mold releasing agent and/or impregnated mold releasing agent fine grains are used for the molding releasing agent fine grains. The mold releasing agent fine grains having the volumetic average grain size of 0.3μm or below are preferable. The vinyl polymer having the glass transition temperature of 60-100 deg.C is preferable. Fluorine-contained ammonium salt is preferably stuck to the toner.</p> |
