PROBLEM TO BE SOLVED: To provide a full-color toner with satisfactory fixing property while obtaining proper gloss. SOLUTION: In the full-color toner comprising at least a binder resin and a colorant is characterized in that a styrene-acryl resin is used for the binder resin, the molecular weight distribution of the toner measured by GPC shows at least one peak and a peak of the main component in the region from 8×10<SP>3</SP>to 5×10<SP>4</SP>molecular weight, the proportion of the component having≤1×10<SP>3</SP>molecular weight is≤7 wt.% in the whole toner and the proportion of the component having≥2×10<SP>5</SP>molecular weight is≤7 wt.%, and the ratio Mw/Mn, wherein Mw is the weight average molecular weight and Mn is the number average molecular weight, satisfies 2≤Mw/Mn≤10.
