<p>A toner for developing electrostatic images is prepared from a binder resin and a hydrocarbon wax. The toner is provided with improved fixability and anti-offset characteristic by controlling the thermal characteristic of the hydrocarbon wax so as to provide a DSC (differential scanning calorimeter) curve, showing an onset temperature of heat absorption in the range of 50 - 110 <o>C and at least one heat absorption peak P1 in the range of 70 - 130 <o>C giving a peak temperature TP1 on temperature increase, and showing a maximum heat evolution peak temperature in the range of TP1 +/- 9 <o>C on temperature decrease. Correspondingly, the toner provides a DSC curve showing a rising temperature of heat absorption of at least 80 <o>C, an onset temperature of heat absorption of at most 105 <o>C and a heat absorption peak temperature in the range of 100 - 120 <o>C, respectively on temperature increase, and showing a heat evolution peak temperature in the range of 62 - 75 <o>C and a heat evolution peak intensity ratio of at least 5x10<-><3> on temperature decrease. <IMAGE></p> |
