Abstract:
1. A liquid developer which comprises an insulation liquid containing a fatty acid monoester and toner particles comprised of a resin material, the resin material containing a first resin component and a second resin component of which weight-average molecular weight Mw 2 is larger than a weight-average molecular weight Mw 1 of the first resin component, wherein the first resin component and the second resin component are characterized in that: the weight-average molecular weight Mw the weight-average molecular weight Mw when an amount of the first resin component contained in the resin material is defined as A (wt %) and an amount of the second resin component contained in the resin material is defined as B (wt %), A and B satisfy a relation: 1.0≦A/B≦9.0.
