ABSTRACT:
A device incorporated in an image recorder for removing the curl of a recording sheet being transported along a transport path. A rotatable elastic roller is disposed on the transport path at the inner side with respect to the curl of the recording sheet. A rotatable pressing member has a polygonal cross-section and has a plurality of curved portions each having a particular radius of curvature on the periphery thereof. The pressing member is located at the outer side with respect to the direction of curl. The center of rotation of the pressing member is parallel to the center of rotation of the elastic roller. A fixing device fixes the pressing member in a position where one of the curved portions presses against the periphery of the elastic roller.
