Abstract:
1. A toner manufacturing method comprising: dissolving or dispersing a toner material into an organic solvent to prepare a toner solution, the toner material containing at least an active hydrogen group-containing compound, a polymer reactive with the active hydrogen group-containing compound, a binder resin, a releasing agent and a coloring agent; emulsifying or dispersing the toner solution into an aqueous medium to prepare an emulsified dispersion; reacting the active hydrogen group-containing compound with the polymer reactive with the active hydrogen group-containing compound in the aqueous medium produce an adhesive base material in the form of particle; and removing the organic solvent, wherein time X (hour) from a point where the organic solvent starts to be removed to a point where the concentration of the organic solvent reaches less than 12% by mass and temperature T (° C.) of the emulsified dispersion at the time X satisfy the relationship 5{exp(−0.2X)+1}≦T≦50X
