Abstract

An elastic fixing roll having an elastic, compliant body material and release surface material is disclosed. The body material comprises porous silicone rubber, fluorosilicone rubber, or fluorocarbon rubber foam, or a porous synthetic polymer foam reinforced with silicone rubber, fluorosilicone rubber, or fluorocarbon rubber. The release surface material is formed of porous polytetrafluoroethylene film containing silicone rubber, fluorosilicone rubber, or fluorocarbon rubber and is bonded to the body material by a non-continuous layer of adhesive. The elastic fixing roll has good strength, resilience, and heat resistance and is suitable for use in hot toner fixing assemblies of copying machines and printing machines
