摘要：
A method for preparing a toner including toner particles is provided. The toner preparation method includes preparing a toner component liquid including at least a binder resin, a colorant and an organic solvent; mixing a resin A having a solubility of less than 2.0 g/100 g in water having a pH of 3.0 at 25° C. while having a solubility of not less than 2.0 g/100 g, a basic material, and water to prepare an aqueous phase liquid, in which the resin A is dissolved; forming droplets of the toner component liquid in the aqueous phase liquid; and removing the organic solvent from the droplets of the toner component liquid to prepare the toner particles.
