Toner
Provided is a toner having an excellent low-temperature fixability and hot offset resistance, a broad fixing temperature latitude in low-temperature areas to high-temperature areas, and a high heat-resistant storage stability. The toner includes toner particles having a core-shell structure in which a shell phase containing a resin A is formed on a core containing a binder resin, a colorant and a wax. In measurement of resin A by a differential scanning calorimetry (DSC), the peak temperature TpA (° C.) of a maximum endothermic peak in the first temperature rise is at least 55° C. but not more than 80° C. In measurement of a viscoelasticity of resin A, the loss elastic modulus at TpA−10 (° C.) is at least 1×107 Pa but not more than 1×108 Pa. In measurement of the viscoelasticity of resin A, the loss elastic moduli at TpA (° C.), TpA+10 (° C.) and TpA+25 (° C.) satisfy specific conditions.
