    摘要： A fixing device includes: a belt member provided to be circularly movable having a width; a first fixing member disposed inside the belt member; a second fixing member disposed in press contact with the first fixing member across the belt member, and forms a passing portion with the belt member, through which a recording medium passes; and a pressing member disposed along a width direction of the belt member and downstream of the passing portion in a moving direction of the belt member, in which the pressing member has a surface and brings the surface in contact with an inner peripheral surface of the belt member to press the belt member against the second fixing member. The surface is curved toward the second fixing member along with a move from an end portion to a center portion in a longitudinal direction of the pressing member.
