Abstract
A heat-pressure fixing device for fixing a toner image is composed of a fixing member, a pressure member and an oil applicator for applying dimethylsilicone oil as a release oil. The fixing member is surfaced with dimethylsilicone rubber having a storage modulus E' satisfying 1.0.times.10.sup.6 dyn/cm.sup.2 <E'<1.5.times.10.sup.7 dyn/cm.sup.2 and a loss modulus E" satisfying 1.0.times.10.sup.5 dyn/cm.sup.2 <E"<7.5.times.10.sup.5 dyn/cm.sup.2, and exhibits a good release performance at a low dimethylsilicone oil application rate of 1-20 mg/A4-size (621 cm.sup.2).
