Abstract
A method for producing resin particles using a dispersion liquid in which a dispersoid mainly made of a resin material is finely dispersed in a dispersion medium, the method comprising a dispersion liquid ejecting step for ejecting the dispersion liquid in the form of droplets and a dispersion medium removing step for removing the dispersion medium from the dispersion liquid in the form of droplets, wherein a granulation prevention agent for preventing or suppressing fine particles derived from the dispersoid from being agglomerated and then granulated is applied to the dispersion liquid.
