摘要：
A method for producing a liquid developer, the method including a step of producing a toner particle by applying a shear force to a mixture of a polyester resin A and B, and a toner particle dispersing agent in a liquid a, wherein the polyester resin A has a number-average molecular weight from 3,000 to 7,000, an acid value of at least 5, and a carboxy group; the polyester resin B has a number-average molecular weight from 4,000 to 20,000 and an acid value of not more than 2; the toner particle dispersing agent has a primary amino group and an amine value of at least 40; the mass ratio (B/(A+B)) for the polyester resin B is 0.3 to 0.9; and the following relationship is satisfied: SP value of liquid a
