<p><P>PROBLEM TO BE SOLVED: To provide a fluorocarbon resin tube which has high durability when used as the surface of a fixing roll and a fixing belt, and also to provide a fixing roll and a fixing belt using this fluorocarbon tube, and an image fixing device having a fixing roll and a fixing belt. <P>SOLUTION: The fluorocarbon resin tube contains polytetrafluoroethylene system fluorocarbon resin as the components. Its maximum wall thickness is 20μmeters or less, and its tensile modulus of elasticity is 900 N/mm<SP>2</SP>or larger in the circumferential direction and the tube axial direction, or each tensile stress when stretched 5% in the circumferential direction and the tube axial direction is 15 N/mm<SP>2</SP>or larger. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
