Elastic rotary body and fixing device with same body

Abstract

Abstract PURPOSE:To improve fixing performance, wear resistance, and specially durability by forming elastic layers of materials obtained by dispersing and mixing a resin material with a rubber material. CONSTITUTION:A fixing roller 1 and a pressure roller 10 are of similar constitution and the elastic layers 4 and 14 and resin layers 6 and 16 are baked on mandrels 2 and 12. Then the resin layers 4 and 14 are formed of materials obtained by dispersing and mixing fluororesin with silicone rubber. The fixing roller 1 which is thus formed has sufficient fixing performance, separating performance, and wear resistance and perform fixation of 300,000 sheets judging from a test of conveying performance, and this exceeds the conventional limit of about 50,000 sheets, thereby improving the durability greatly.
