Abstract
A fixing device includes a fixing member, a pressing member, a heat source, and a reflecting member. The pressing member presses and contacts an outer circumferential surface of the fixing member. The heat source is disposed inside a loop of the fixing member. The reflecting member includes a reflecting portion, a pressure receiving portion, and an extending portion. The reflecting portion reflects heat toward an inner circumferential surface of the fixing member. The pressure receiving portion receives a pressing force of the pressing member via the fixing member. The extending portion extends from an area upstream to an area downstream from the nip portion in a direction of rotation of the fixing member and facing the inner circumferential surface of the fixing member. The reflecting member is in non-contact with one or more of members disposed inside the loop of the fixing member, at least when the fixing member rotates.
