<p>PROBLEM TO BE SOLVED: To provide a resin compsn. for a toner suitable for use as a full-color toner without deteriorating preservability, fixabilirty, anti-offsetting property, pulverizability and transparency or causing filming on a photoreceptor and to provide a toner. SOLUTION: Wax having a wt. average mol.wt. of 400-700, 60-100 deg.C peal by differential scanning calorimetry and 5-30dmm penetration at 35 deg.C is incorporated by 0.1-10wt.% into a vinyl copolymer composed of a styrene monomer and a (meth)acrylic ester monomer, having a peak within the mol.wt. range of 3×10<3> to 1.5×10<4> in the mol.wt. distribution by gel permeation chromatography and having a wt. average mol.wt. of <=150,000 to obtain the objective resin compsn, for a toner.</p> |
