<p>PROBLEM TO BE SOLVED: To manufacture a toner for electrostatic charge image development having excellent heat-resistant storage property more efficiently (with less energy).SOLUTION: A toner for electrostatic charge image development includes a plurality of toner particles. The plurality of toner particles each include a binder resin. The plurality of toner particles are dispersed into a water at pH12 to prepare a toner dispersion with a solid content concentration of 10 mass%, and when the temperature of the toner dispersion is changed from a temperature lower than the glass transition point of the binder resin by 15°C to a temperature higher than the glass transition point of the binder resin by 15°C, the amount of change in pH of the toner dispersion is 2.5 or more.</p> |
