PURPOSE:To improve fixing performance and reduce a driving load by forming a tube for attachment which has a surface contacting a recording material tightly and an internal surface with slidability for a roller body. CONSTITUTION:When a fixing roller 1 consists of a fixing roller body manufactured individually and a heat-stripping resistance elastic coating 15, the contacting surfaces of the coating 15 and the surface layer sheet 14 of the roller body are both made of silicone rubber and the coefficient of friction is high. For this purpose, resin and oily resin having small coefficients of friction, etc., are provided at least on the internal surface of the coating 15. Further, a silicone lubricant is interposed between the surface layer sheet 14 and coating 15 to realize the relative movement between the roller body and the surface coating. Consequently, a pressure roller 2 is driven and the fixing roller 1 is driven to perform the fixation to improve the fixing performance and reduce the driving load. |
