<p>A toner for developing electrostatic images is prepared from a binder resin, a colorant or magnetic material, and a wax component. The toner is provided with improved low-temperature fixability anti-electrostatic offset characteristic, anti-blocking characteristic and anti-offset characteristic by controlling the thermal characteristic of the wax component so as to provide a DSC (differential scanning calorimeter) curve on temperature increase, showing a minimum onset temperature of heat absorption of at least 50 <o>C and at least two heat absorption peaks including a largest and a second largest peaks, different from each other in peak temperature by at least 15 <o>C, wherein a lower-temperature heat absorption peak P1 of the two peaks shows a half-value width of at most 20 <o>C and a higher-temperature heat absorption peak P2 shows a half-value width of at most 20 <o>C, and wherein the peak P1 shows a higher half-width temperature and the peak P2 shows a lower half-width temperature different from the higher half-width temperature of the peak P1 by at least 5 <o>C. <IMAGE></p> |
