PURPOSE:To improve durability, fixing properties, economy, etc., by providing a rotating body for fixation with the 1st layer made of a heat-resistant elastic body and the 2nd layer made of a heat-resistant porous elastic body. CONSTITUTION:A pressing roller 2 to be pressed against a heat fixing roller 1 which has a heating means 4 is formed by coating a mandrel 7 with a primer 72, adhering a silicone sponge layer 8 onto it, and applying RTV silicone rubber into an elastic coating layer 9. In this constitution, the coating layer 9 has higher heat conductivity than the sponge layer 8, so the waiting time during induction period is shortened and the heat conductivity of the sponge layer 8 is inferior to that of the coating layer 9. Therefore, the heating value required to hol the pressing roller 2 itself at specified temperature through the heat fixing roller is reduced, while improving thermal efficiency. |
