PROBLEM TO BE SOLVED: To provide an environment-friendly liquid developer having excellent preservability while having excellent fixability of toner particles to a recording medium, and to provide an image forming apparatus using the liquid developer. SOLUTION: The liquid developer is obtained by dispersing toner particles into an insulating liquid, and comprises fatty acid triglyceride and fatty acid monoester. The fatty acid triglyceride and fatty acid monoester both comprise unsaturated fatty acid as fatty acid components, and the content of the fatty acid triglyceride in the insulating liquid is 51 to 80 wt.%. The viscosity of the liquid developer at 25°C measured according to JIS Z8809 using an vibration type viscometer is preferably 50 to 1,200 mPa s. COPYRIGHT: (C)2008,JPO&INPIT
