Abstract
A fixing device that fixes an image on a recording medium includes a rotatable endless belt, deployed in a loop supported by rollers, a nip forming member provided inside the loop formed by the belt, a support member that supports the nip forming member, a counter rotation body disposed outside the loop formed by the belt and configured to form a nip with the belt by being in contact with the nip forming member through the belt, and a heat source configured to heat the belt directly by a radiant heat except at the nip. The support member includes a base portion that contacts the nip forming member and two arms extending from the base portion in a direction away from the nip forming member to partially surround a part of heat generating portion of the heat source.
