Abstract:
1. A decurler device, comprising: a first roller with elastic deformability including a first rotational shaft and configured to rotate about the first rotational shaft as an axial center; a second roller including a second rotational shaft in parallel with the first rotational shaft and configured to rotate about the second rotational shaft as an axial center, to elastically deform the first roller by being pressed by the first roller to form a curved nip portion between the second roller and the first roller, and to convey a sheet; a support unit configured to pivotally support the first and second rotational shafts to rotatably support the first and second rollers and including a third rotational shaft in parallel with the first rotational shaft, the support unit being rotatable about the third rotational shaft as a center axis; a unit drive section configured to rotate the support unit; a roller drive section configured to rotate the second roller; and a drive controller configured to control the unit drive section and the roller drive section to rotate the support unit when the sheet is conveyed by the curved nip portion.
