A fixing device includes: a rotating member supporting section supporting a first rotating member rotatably and movable in direction in which the first rotating member approaches and leaves a second rotating member; a compression spring pushing the rotating member supporting section in the direction of approaching the second rotating member; and a pressing member pressing the compression spring to the rotating member supporting section. The device further includes: a first spring contact member contacting the compression spring and movable in a compression-and-expansion direction of the compression spring relative to the rotating member supporting section; a first adjustment screw adjusting a position of the first spring contact member; a second spring contact member contacting the compression spring and movable in a direction inclined to the compression-and-expansion direction, relative to the pressing member; and a second adjustment screw adjusting a position of the second spring contact member relative to the pressing member.
