Abstract

PURPOSE:To obtain excellent fixation, proper elasticity, and sufficient durability by mixing a resin material with 2nd elastic layers and forming 1st and 2nd elastic layer and a resin layer in decreasing thickness order. CONSTITUTION:The elastic rotary body has the 1st elastic layers 4 and 14 which are formed inside and have good heat conductivity, the 2nd elastic layers 5 and 15 which are formed as the external layers of the 1st elastic layers and have good heat insulation, and the resin layers 6 and 16 which are formed as jackets. Then the resin material is mixed with the 2nd elastic layers 5 and 15, and the 1st elastic layers 4 and 14, 2nd elastic layers 5 and 15, and resin layers 6 and 16 are formed in the thickness decreasing order. Further, the 1st and 2nd elastic layers 4 and 14, and 5 and 15 are formed of silicone rubber or fluororubber, the resin material mixed with the 2nd elastic layers 5 and 15 is fluororesin, and the jacket resin layers are formed of the fluororubber to obtain a preferable effect. Consequently, even if rubber deterioration occurs, desired proper rubber characteristics are obtained on the whole and problems such as the curling, wrinkling, and low-temperature offset which are caused at the time of conveyance and fixation are solved.
