Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for producing an electrostatic charge image developing toner, by which a volatile substance contained in the toner and causing problems such as odor is efficiently reduced.SOLUTION: In the method for producing the electrostatic charge image developing toner, toner particles generated by a wet method are supplied to a vessel for performing a drying process, and then vacuum vapor of 0.6 to 5 m/hr per kg of the toner particles is supplied from the bottom of the vessel into the vessel to remove the volatile substance included in the toner particles.
