装置。[Claims for Utility Model Registration] An elastic roller made of an elastic body whose shaft center is fixedly supported by a drive shaft, and a rigid body made of a rigid body whose shaft center is integrally supported by another drive shaft. In a decurling device in which a recording sheet is passed through a nip portion in a state where rollers are nipped in pressure contact with each other on their outer circumferential surfaces, conveyance rollers are mounted on the drive shafts at both ends of the elastic roller in the axial direction to achieve a predetermined friction. The core conveying roller is loosely fitted with resistance, and its outer circumferential surface touches the outer circumferential surface of the rigid roller, and the elastic roller does not rotate when paper is passing through, but only at a predetermined angle when paper is not passing through. A decurling device for an image forming apparatus that rotates.
