<p>PROBLEM TO BE SOLVED: To obtain an electrophotographic toner fixable at a low fixing temp., causing no problem even on anti-offsetting property in practical use and excellent in fixing strength to transfer paper. SOLUTION: This electrophotographic toner contains Fischer-Tropsch wax and a styrene-(meth)acrylic ester copolymer as a bonding resin and has at least two max. values in its gel permeation chromatogram. Mol.wt. at one of the max. values is >=8×10<5> and that at the other is 3,000-10,000.</p> |
