US Patent 9377705 Toner

A toner containing a toner particle containing a binder resin, wherein the binder resin contains a styrene-acrylic resin and a crystalline resin, and the crystalline resin is a block polymer or a graft polymer in which the mass ratio between the crystalline segment and an amorphous segment is 30:70 to 90:10, and wherein, in the total heat flow measured for the binder resin by a temperature-modulated differential scanning calorimeter, the peak temperature of an endothermic peak is from 55.0° C. to 90.0° C., and the percentage of the endothermic quantity of the endothermic peak in the reversing heat flow with respect to the endothermic quantity of the endothermic peak in the total heat flow is from 0.0% to 35.0%.
