The present invention provides a toner and a developer manufacturing method capable of reducing the particle size and controlling the shape and forming a good image. A dispersion having a granular mixture obtained by mixing, melt-kneading, and further pulverizing a toner material dispersed in an aqueous medium is selected from among acids having a surface active function and salts having a surface active function. A method for producing a toner and a developer, wherein at least one surfactant is added in an amount of 0.1 to 5% by weight based on the total weight of the developer, and a mechanical shearing force is applied in a heated and melted state to atomize the granular mixture.
