Claim Text:
1. A fixing device comprising: a fixing belt configured to be rotatable; a pressuring member configured to be rotatable and to come into pressure contact with the fixing belt so as to form a fixing nip; a heat source arranged at an inside in a radial direction of the fixing belt and configured to radiate a radiant heat; a reflecting member configured to reflect the radiant heat radiated from the heat source to an inner circumference face of the fixing belt; a pressing member configured to press the fixing belt to a side of the pressuring member; and a supporting member configured to support the pressing member, wherein the reflecting member is arranged between the heat source and the supporting member and configured to be curved or bent so that a middle part of the reflecting member projects toward a side of the heat source and both end parts of the reflecting member project toward a side remote from the heat source, straight lines connecting a center of the heat source with both end parts of the supporting member pass through the reflecting member, wherein the supporting member includes: an upstream side stay; and a downstream side stay arranged at a downstream side of the upstream side stay in a conveying direction of a recording medium, wherein the upstream side stay includes: an upstream side base plate; and an upstream side support plate bent from the upstream side base plate to an upstream side in the conveying direction of the recording medium, wherein the downstream side stay includes: a downstream side base plate fixed to the upstream side base plate by a screw; and a downstream side support plate bent from the downstream side base plate to the downstream side in the conveying direction of the recording medium.
