Patent ID: 7691553

Claim:
A method for manufacturing a toner comprising: a kneading step for heating and melt-kneading a toner composition containing at least a binder resin and a colorant to produce a kneaded material in which at least the colorant is dispersed in the binder resin; and a granulating step for mixing the kneaded material with a water-based medium, and then a mixture obtained is heated to disperse the kneaded material into the water-based medium in a state in which the kneaded material is softened, wherein a granulating temperature at the granulating step is set to a temperature at which a loss tangent obtained by dividing a loss elastic modulus G″ of the kneaded material by a storage elastic modulus G′ reaches a loss tangent value A of 0.5 or more and less than 5.0, the loss tangent being measured at a setting frequency of 0.1 Hz, thereby a toner composed of toner particles whose average spherical degree is 0.90 or more and 0.97 or less is obtained.
