TONER

PROBLEM TO BE SOLVED: To provide toner in which developability, transferability, fixability and storage stability are improved, and with which image glossiness is made uniform in printing on both sides. SOLUTION: The toner includes: toner particles at least containing a binder resin, a coloring agent and wax, and inorganic fine powder, and the toner particles can be obtained by being produced in an aqueous medium. In the micro compression test to the toner at a measurement temperature of 25°C, provided that the displacement (μm) obtained after applying the maximum load of 2.94×10-4N to the toner 1 particle at an application rate of 9.8×10-5N/sec is defined as a displacement X2, the displacement (μm) obtained, after the application of the maximum load, by leaving the same at the maximum load for 0.1 s is defined as the maximum displacement X3, the displacement (μm) obtained when the load is made zero by removing the load at a load removing rate of 9.8×10-5N/sec after the leaving for 0.1 s is defined as X4, and the percentage of the elastic displacement (X3-X4) to the maximum displacement X3[(X3-X4)/X3×100: recovery rate] is defined as Z(25)(%), the relation of 40≤Z(25)≤80 is satisfied. In the toner, the glass transition temperature (TgA) measured by a differential scanning calorimetry (DSC) device is 40 to 60°C, the maximum endothermic peak temperature (P1) is 65 to 100°C, the glass transition temperature (TgA) and the maximum endothermic peak temperature (P1) satisfy the relation of 10≤(P1-TgA)≤60, and the wax has a specified structure.
