By use of the toner, a highly precise image may be obtained.In a toner for developing an electrostatic charge image prepared by a wet process, the dielectric loss factor of the toner particles is 100 or less. In addition, when the toner particles are dissolved in an organic solvent and mixed with deionized water, the electrical conductance of the solution is desirably 100 ms or less and the surface tension thereof is desirably 20 mN or more. The toner may be obtained by forming agglomerated particles with stirring in a dispersion in which resin particles are dispersed to granulate; heating the toner particles to Tg or higher of the binder resin; stirring; and cleaning. With a wet process, the added stabilizing agent such as a surfactant can be removed.
