The present invention relates to a toner which has good property such as fixability, coloring power, developability, durability, and environmental stability and so on. More specifically, the present invention relates to a color toner containing at least a binder resin, a colorant, and a wax, in which: a wax concentration of an extract obtained by dispersing the toner into n-hexane at a concentration of 15 mg/cm3at 23° C. and by subjecting the resultant dispersion to extraction treatment at 23° C. for 1 minute is in the range of 0.080 to 0.500 mg/cm3; an average circularity of particles each having a circle-equivalent diameter of 3 μm or more in the toner is in the range of 0.925 to 0.965; and a content of the wax is in the range of 1 to 15 parts by mass with respect to 100 parts by mass of the binder resin.
