Abstract
A decurler device corrects a curl of a sheet. The decurler device includes a first roller, a second roller and a support unit. The first roller rotates about a first rotational shaft as an axial center. Further, the first roller is elastically deformable. The second roller rotates about a second rotational shaft in parallel with the first rotational shaft as an axial center. Further, the second roller is pressed by the first roller to elastically deform the first roller, thereby forming a curved nip portion between itself and the first roller. The second roller rotates to convey a sheet. The support unit rotatably supports the first and second rollers. Further, the support unit is rotatable about a third rotational shaft in parallel with the first rotational shaft as an axial center. The support unit rotates when a sheet is conveyed with it nipped by the nip portion.
