Abstract: A fixing device includes a fixing member, a pressure roller, a discharge rollers pair, a discharge guide, and an actuator. The fixing member is heated by a heat source. The pressure roller forms a pressurized region. The discharge rollers pair includes an upper roller and a lower roller, and conveys the sheet passed through the pressurized region. The discharge guide guides the sheet passed through the pressurized region to the discharge rollers pair. The actuator includes a rotating shaft supported by the discharge guide rotatably and movably in an axial direction and a detection piece extending radially from the rotating shaft, and rotated by the sheet passed through the pressurized region to detect the sheet. The discharge guide has a slit in which the detection piece is housed to regulate a moving of the detection piece in a width direction of the sheet.

Abstract: A fixing device includes a heating rotating body, a pressure rotating body, and a fixing frame. The fixing frame supports the heating rotating body and the pressure rotating body. The fixing frame includes a pair of side plates and a plurality of stays. The side plates are disposed to face each other, and supports both axial end portions of the heating rotating body and both axial end portions of the pressure rotating body. The stays are disposed between the side plates. In a XYZ coordinate in which an axis along a direction in which the side plates face each other is defined as the X-axis, and axes perpendicular to the X-axis and perpendicular to each other are defined as the Y-axis and the Z-axis, each of the stays is fastened to the side plates at least two axial directions of the three axial directions of the XYZ coordinates.
