A fixing device includes a heating member heating a recording medium to fix a developer image thereto; an endless heating belt rotatably wrapped around the heating member and heating the medium; a rotating member around which the belt is wrapped and having a fixed first axial end; a position detecting unit detecting a position of the belt when moved in first and second opposite directions parallel to an axial direction of the rotating member; and a controller controlling a rotational movement angle by which a second axial end of the rotating member is rotationally moved about the first end in an axis-intersecting direction based on information from the position detecting unit when the belt is moved in the first and second directions so that first and second speeds for respectively moving the belt in the first and second directions are made equal to or close to each other. |
