ELASTIC FIXING ROLL WITH EXCELLENT RELEASE PROPERTY

摘要

An elastic roll of the first embodiment comprises an elastic body layer formed in a thickness not less than 200 .mu.m on a metal core bar; and a covering layer with a release property formed in a thickness ranging from 3 .mu.m to 200 .mu.m on the surface of the elastic body, the covering layer being formed of a composite material composed of fibrillated polytetrafluoroethylene and elastomer having releasing properties. An elastic fixing roll of second embodiment comprises a heat-conductive elastic body layer formed of heatresistant elastomer in a thickness not less than 200 .mu.m on a metal core bar; an oil-resistant layer formed of oil-resistant elastomer in a layer thickness ranging from 3 .mu.m to 200 .mu.m on the elastic body layer; and a covering layer having a release property and formed of a composite material composed of fibrillated polytetrafluoroethylene and elastomer with a release property in a thickness ranging from 3 .mu.m to 200 .mu.m on the oil-resistant layer.
