    Abstract: The present invention provides a fixing device including a flexible cylindrical rotary member and an inner-surface opposing portion that opposes an inner surface of the rotary member at an end portion of the rotary member in a generatrix direction. The inner-surface opposing portion moves upstream in a recording material conveying direction in accordance with lateral shift of the rotary member in the generatrix direction. This restricts the lateral shift of the rotary member.

    Abstract: A sheet conveyance device includes first and second discharge portions to discharge sheets, first and second stacking portions on which sheets are to be stacked, and a control unit to control the second stacking portion to move between a first position and a second position. The first position is that a downstream side of the second stacking portion is positioned and inclined upwardly with respect to an upstream side of the second stacking portion in a sheet conveyance direction of the sheets discharged from the second discharge portion. The second position is that the downstream side of the second stacking portion is positioned on a lower side of the first position of the downstream side of the second stacking portion.

    Abstract: A fixing device includes first and second members, a frame supporting the second member, and two pressure mechanisms provided on either end of the first member. The mechanism includes a lever having one end supported by the frame in a rotatable manner in a pressure direction, and a helical compression spring disposed between a first spring support provided on the other end of the lever and a second spring support on the frame. At least one of the first and second spring supports includes a first area and a second area closer to the spring in the axial direction than the first area, the first area is in contact with an area of the spring close to a winding end of the spring, and the second area is in contact with an area of the spring farther away from the winding end in a winding direction than the first area.
