PROBLEM TO BE SOLVED: To provide a flash fixing electrophotographic toner which has high infrared absorbing ability, good flash fixing property and is economically inexpensive. SOLUTION: The polymerized toner containing at least the resin component, a colorant, and an infrared absorber, which is obtained by directly or further using particles obtained by coagulating the resin particles obtained by polymerization, The absorbent is added to the polymerization system or the coagulation treatment system after the fine dispersion treatment, and the infrared absorbent has a wavelength of 75. A polymer having a maximum absorption wavelength in the range of 0 to 1100 nm, and wherein the amount of the infrared absorbent added is in the range of 0.01% by weight to 5% by weight based on the total weight of the toner. toner. |
