PROBLEM TO BE SOLVED: To provide a liquid developer capable of fixing toner particles on a recording medium at a low temperature and a high speed, capable of tightly fixing the toner particles on the recording medium, and not harmful to the environment, and to provide an image forming apparatus using such a liquid developer. SOLUTION: The liquid developer is a liquid developer in which toner particles consisting mainly of a resin material are dispersed in an insulating liquid, wherein the insulating liquid contains a fatty acid monoester and a fatty acid triglyceride, the fatty acid monoester and the fatty acid triglyceride containing an unsaturated fatty acid as a fatty acid component, a content X [wt.%] of the fatty acid monoester and a content Y [wt.%] of the fatty acid triglyceride in the insulating liquid satisfy the relationship of 0.01≤X/Y≤1.0, and the resin material has a glass transition temperature Tg of 15-70°C and a softening temperature Tf of 80-140°C.
