摘要： An object is to provide an electrostatic charge image developing toner and an image forming method using the same capable of maintaining image properties for a long duration, which exhibit not only sufficient transparency and chromaticness, accompanied with high color reproduction and excellent charging characteristic, but also excellent heat resistance, together further with excellent light fastness and sufficient image holding ability. Disclosed is an electrostatic charge image developing toner of the present invention comprising a binder resin for toner particle formation and colorant particles dispersed in the binder resin, wherein the colorant particles comprise a dye and an antioxidant. Further, the electrostatic charge image developing toner wherein a volume-based median particle diameter of the colorant particles is preferably 10-100 nm, and also the dye contained in the colorant particles is preferably an oil-soluble dye or a metal chelate dye.
