Zusammenfassung:A fixing device (18) includes a fixing belt (22), a pressuring member (23), a heat source (24) and a reflecting member (25). The fixing belt (22) is arranged rotatably around a rotation axis (A). The reflecting member (25) reflects the radiant heat radiated from the heat source (24). The fixing belt (22) has a passing region (51) and a non-passing region (52). Through the passing region (51), a recording medium passes. The non-passing region (52) is arranged outside the passing region (51) in a direction of the rotation axis (A). The reflecting member (25) has a first reflecting part (64) and a second reflecting part (65). The first reflecting part (64) is arranged at an inner circumferential side of the passing region (51). The second reflecting part (65) is arranged at an inner circumferential side of the non-passing region (52). Roughness of a face at the heat source (24) side of the second reflecting part (65) is larger than roughness of a face at the heat source (24) side of the first reflecting part (64) .
