ABSTRACT:
There is provided a toner for developing a latent electrostatic image, obtained by a method containing: ejecting a toner composition fluid from an ejection hole so as to make the toner composition fluid into droplets; and solidifying the droplets in an atomizing space so as to form solid particles, wherein the toner composition fluid contains at least a colorant formed by reacting a polymer containing 10 mol % or more of a monomer unit having a sulfonic acid group or a salt thereof, or a monomer unit having a sulfuric acid group or a salt thereof as a constitutional unit, and a basic dye.
