A toner production method that reuses a fine particle toner having a particle diameter failing to meet a predetermined standard diameter which is generated in pulverizing and classifying processes carried out for a toner material including at least a binder resin, release agent and pigment. The method includes granulating the fine particle toner by means of a granulating apparatus so as to increase a loose apparent density of the fine particle toner from the range of 0.05 g/cc to 0.25 g/cc to the range of 0.30 g/cc to 0.60 g/cc, in which wherein the granulating apparatus contains two left and right press rolls having the same diameters, the two press rolls having a rotational speed ratio of 0.40 to 0.95.
