Abstract
A method for producing a developing agent, includes preparing a dispersion of particles containing a binder resin and a coloring agent and forming toner particles by aggregating and fusing the particles, in which the number of coarse particles having a particle size of 0.6 μm or larger after the solid concentration of the dispersion of particles is adjusted to 1 ppm is less than 3,000 per μL.
