PROBLEM TO BE SOLVED: To provide a method for producing a toner to obtain a small-particle toner with less amount of coarse particles to be produced, and having a sharp particle size distribution, and obtain a print image having high resolution and free from unevenness in a half tone image. SOLUTION: In the method for producing a toner for developing electrostatic charge image composed of a particle aggregate at least including polymer primary particles, a formalin polycondensate of naphthalene sulfonate is added.
