FIXING DEVICE AND IMAGE FORMING APPARATUS

摘要

A fixing device includes a fixing member, a pressuring member, a heat source, a heat conducting member, a reflecting member and a contacting/separating mechanism. The fixing member is arranged rotatably. The pressuring member is 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. The heat source is arranged at an internal diameter side of the fixing member to emit radiant heat. The heat conducting member comes 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. The reflecting member reflects the radiant heat emitted from the heat source toward the heat conducting member. The contacting/separating mechanism makes the heat conducting member and reflecting member come into contact with/separate from each other.
