Claim Text:
1. A fixing device comprising: a fixing member arranged rotatably; a pressuring member arranged at an external diameter side of the fixing member to come into pressure contact with the fixing member so as to form a fixing nip, and arranged rotatably; a heat source arranged at an internal diameter side of the fixing member to emit radiant heat; a heat conducting member coming into contact with an inner circumference face of the fixing member to absorb the radiant heat emitted from the heat source and to conduct it to the fixing member; a reflecting member reflecting the radiant heat emitted from the heat source toward the heat conducting member; and a contacting/separating mechanism making the heat conducting member and reflecting member come into contact with or separate from each other, wherein the heat conducting member includes: a first main body part coming into contact with the inner circumference face of the fixing member; and first extending parts extending from both end parts of the first main body part toward a side of the reflecting member, the reflecting member includes: a second main body part facing to the first main body part across the heat source; and second extending parts extending from both end parts of the second main body part toward a side of the heat conducting member, the first extending part and second extending part are arranged so as to be overlapped as viewed from the heat source in both contacting and separating condition of the heat conducting member and reflecting member.
