A toner is provided which has toner particles and an inorganic fine powder; the toner particles being obtained by suspension polymerization using a specific polar resin. The toner is a toner in which; where, in displacement levels found in a micro-compression test in which a force is applied to a toner single particle at a loading rate of 9.8 x 10 -6 N/sec to measure a displacement level (μm) at a point of time where the force has reached a maximum force of 4.90 x 10 -4 N, the displacement level of the toner at a measurement temperature of 25 °C is represented by X(25) and the displacement level of the toner at a measurement temperature of 50 °C by X(50), and the number average particle diameter of the toner is represented by D (μm), the X(25), X(50) and D satisfies the relations: 0.10 ≤ X(25)/D ≤ 0.35 (1) 30 ≤ [X(50)-X(25)]/X(25) x 100 ≤ 150 (2). |
