Color toner

Abstract

To provide a color toner which is effective in mitigating contamination of a charging member, which is good at low temperature fixing in high-speed copying, and which is excellent in blocking resistance and electrification stability in continuous copying. Provided is a color toner containing at least a binder resin, a colorant, and a releasing agent, in which: (i) the binder resin contains at least a polyester unit; (ii) a weight average particle diameter of the color toner is greater than 6.5 μm and equal to or less than 11 μm; (iii) an average circularity A of particles in the color toner each having a circle-equivalent diameter of 3 μm or more satisfies the relationship of 0.915≦A≦0.960; (iv) a permeability B (%) of the color toner in a 45 vol % aqueous solution of methanol satisfies the relationship of 10≦B≦70; and (v) an endothermic curve obtained through differential thermal analysis (DSC) measurement of the color toner has one or multiple endothermic peaks in the temperature range of 30 to 200° C., and a temperature Tsc of the highest endothermic peak of the one or multiple endothermic peaks satisfies the relationship of 65° C.<Tsc<105° C.
