METHOD FOR PRODUCING PIGMENT DISPERSION LIQUID AND METHOD FOR PRODUCING ELECTROSTATIC IMAGE DEVELOPING TONER

The present disclosure relates to a method for producing a pigment dispersion liquid and a method for producing a toner for developing an electrostatic charge image. This method for producing a pigment dispersion comprises: a first step for obtaining a mixture B by wet-dispersing a mixture A containing an organic pigment, a flame retardant, a dispersant, and an aqueous medium using a medium dispersion machine; and a second step in which a mixture C is obtained by performing wet dispersion on the mixture B using a media dispersion machine, the media dispersion machine in the first step and the second step being a ring-type media dispersion machine. The number average particle diameter MA of the media particles in the media dispersion machine in the first step and the number average particle diameter MB of the media particles in the media dispersion machine in the second step satisfy the following formula (1) and the following formula (2). Formula (1): 0.5 mm > = MA > MB > = 0.05 mm; formula (2): 0.3 mm > = MB
