PROBLEM TO BE SOLVED: To provide toner for electrostatically charged image development which is free of deterioration of a contained infrared-ray absorber even when left as it is for a long period and further to provide toner for light fixation which varies in neither charging properly nor fixing properly even when left as it is for a long period and invisible toner that makes it possible to read a signal of infrared rays for a long period when an image is formed as an invisible image. SOLUTION: Disclosed is the toner for electrostatically charged image development which contains at least binding resin and the infrared-ray absorber, the toner for electrostatically charged image development containing copper-containing phenolate as an antioxidant agent together with the infrared-ray absorber.
