<p>PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner which can highly satisfy the requirements of fixing property and offset resistance while maintaining high developing property in various environments for repeated use, and which does not cause deposition or sticking of the toner or a paper powder component on a pressurizing roller or a heating roller of a fixing machine. SOLUTION: In the electrostatic charge image developing toner containing at least a binder resin and a wax, the toner contains two kinds of waxes (A) and (B) having the following properties. The wax (A) shows the endothermic main peak measured by differential scanning calorimeter(DSC) at 50 to 130 deg.C and has <=20 deg.C half-width of the endothermic main peak, while the wax (B) is a polypropylene wax having 1 to 30 mg KOH/g acid value.</p> |
