  • Publication number: 20220171304
    Abstract: A toner contains toner particles that include a binding resin, a crystalline resin, an ester wax and a dispersant. The binding resin includes an amorphous polyester resin, and the dispersant includes an acrylic copolymer resin or a hybrid resin of the amorphous polyester resin and a styrene resin. When an endothermic peak temperature that is derived from the ester wax in a temperature rise is represented by T1, an exothermic peak temperature that is derived from the ester wax in cooling is represented by T2, a peak temperature of the crystalline resin is represented by Tc and the endothermic peak temperature, the exothermic peak temperature and the peak temperature are measured with a differential scanning calorimeter, T2<Tc<T1 is satisfied, and T1 is greater than 65° C. and less than 85° C.
