Abstract:
1. A method of manufacturing toner, comprising: preparing a first liquid by dissolving or dispersing toner components in an organic solvent, the toner components comprising one or both of a binder resin and a precursor thereof; preparing a second liquid by dispersing the first liquid in a first aqueous medium comprising a dispersant; producing primary particles by removing the organic solvent from the second liquid; washing the primary particles; preparing a third liquid by dispersing the washed primary particles in a second aqueous medium and heating the second aqueous medium while or after dispersing the washed primary particles therein; and producing toner particles by adding a charge controlling agent to the third liquid, wherein the following inequation is satisfied: wherein Sa represents a BET specific surface area of the primary particles in the third liquid and Sb represents a BET specific surface area of the toner particles stored for 2 weeks at 40° C., 70% RH.
