    Abstract: PROBLEM TO BE SOLVED: To provide a thermal fixing type electrophotographic developer excellent in meltability at a low temp., releasability in thermal fixing, particularly releasability and anti-blocking property in low temp. fixing, free from offset phenomenon and the contamination of a carrier, a photoreceptor, a heating roller or the like and then, capable of being used as the essential component of an electrostatic toner. SOLUTION: The developer contains a polyolefin wax (A) having a weight average molecular weight(MW) of 3,000-50,000 found by a gel permeation chromatography(GPC) and containing 0.2-0.8 mol% different kind bond caused by no 1,2-insertion reaction in polymerizing an α-olefin of a raw material monomer, a binder (B) and a coloring agent (C).
