1. A curl eliminating device, comprising:
a decurl roller pair including a first roller contacting with a non-image formed side of a recording medium, the first roller being an elastic roller including an elastic layer formed on an outer circumference surface thereof, and a second roller configured to be pressed to contact with the outer circumference surface of the first roller and configured to contact with an image formed side of the recording medium, the second roller having a diameter smaller than that of the first roller and hardness higher than that of the first roller, the decurl roller pair configured to correct curl of the recording medium; a cleaning member for cleaning the second roller by contacting with the second roller from a side thereof opposite to a nip portion between the first and second rollers; a pair of frames rotatably supporting both end portions of rotation shafts of the first roller, the second roller, and the cleaning member; a pressure contact mechanism for pressing the cleaning member to contact with an outer circumference surface of the second roller from the side opposite to the first roller; and a pressure adjustment mechanism for adjusting an interval between the rotation shafts of the first roller and the second roller, wherein the rotation shafts of the first roller and the cleaning member are supported so as to be slidable in a direction toward or away from the second roller along slots formed in the frames, and a press contact force acting from the first roller to the second roller by the pressure adjustment mechanism and a press contact force acting from the cleaning member to the second roller by the pressure adjustment mechanism cancel each other. |
