    摘要: In a process for producing toner particles by dispersing in an aqueous medium a polymerizable monomer composition containing at least a polymerizable monomer and a colorant and carrying out polymerization by the use of a polymerization initiator, the concentration of alcohol having 4 to 6 carbon atoms in the aqueous medium is so adjusted as to be from 500 ppm to 2,000 ppm when the polymerization conversion of the polymerizable monomer composition is 30%, and to be from 2,300 ppm to 10,000 ppm when the polymerization conversion of the polymerizable monomer composition is 97%.

    摘要: 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 9.8×10−6 N/sec to measure a displacement level (μm) at a point of time where the force has reached a maximum force of 4.90×10−4 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)×100≦150  (2).
