    Abstract: Disclosed is a method for producing an electrostatic charge image developing toner, including: drying wet toner base particles to produce the electrostatic charge image developing toner. The toner base particles contain an amorphous polyester that is a polycondensate of a polyvalent carboxylic acid and a polyhydric alcohol. In the amorphous polyester, a content of a structural unit derived from bisphenol A or a bisphenol A derivative is 10 mol % or less with respect to total moles of a structural unit derived from the polyhydric alcohol. The drying comprises drying the wet toner base particles with an airflow in a dryer. A temperature of the airflow is equal to or higher than 60° C. A velocity of the airflow is greater than or equal to 5 m/sec.

    Abstract: In an image forming method according to the present invention, an image is formed by removing residual charge from the image on an image recording medium. The image forming method includes formation of an image for forming a toner image by fixing a toner on the image recording medium and application of voltage from a voltage applier, the voltage having a polarity reverse to a polarity of a surface potential of the toner image. The toner includes toner base particles and an external additive. The toner base particles include a crystalline polyester resin.
