A fixing apparatus includes: first and second pressure members each of which is in contact with an inner circumferential surface of an endless belt and nips the endless belt between itself and a cylindrical member; a frame supporting the first and second pressure members; an actuator that moves the first pressure member between a first position and a second position in a movement direction of a portion, of the endless belt, positioned between the first and second pressure members; and an elastic body that generates nipping force to nip the endless belt. The nipping force by the elastic body is generated between the cylindrical member and the first and second pressure members, both in a case that the first pressure member is positioned in the first position and a case that the first pressure member is positioned in the second position.
