<p>PROBLEM TO BE SOLVED: To make it possible to enhance both of resistance to offset and resistance to filming at the same time by incorporating a specified nonoxidized polypropylene wax and a specified oxidized polypropylene wax as wax components. SOLUTION: The nonoxidized polypropylene wax has a heat absorption peak in the range of 130-138 deg.C, preferably, 130-137 deg.C in a thermal analysis and a peak of 7,500-12,000 in a molecular weight distribution based on the weight, preferably, 8,000-11,500, and the oxidized polypropylene wax has a heat absorption peak in the range of 138-150 deg.C, preferably, 139-146 deg.C in the thermal analysis, and the sum of both waxes is 0.5-5 weight %, of a binder resin, preferably, 0.5-4 weight %, and it is preferred that both waxes are melt-blended and this blend is used for the color toner.</p> |
