FEEDING DEVICE AND FEEDING METHOD,AND IMAGE FORMING DEVICE

摘要

A sheet feeding device for feeding a continuous sheet to a sheet treatment part for applying a specified treatment to the continuous sheet, comprising drive rollers for feeding, by a frictional force, the continuous sheet in a normal direction to the sheet treatment part and in a direction reverse to the normal direction, a pre−centering mechanism disposed on the upstream side of the drive roller in the normal direction and limiting the position of the continuous sheet in the normal direction and in a direction orthogonal to the direction reverse to the normal direction by allowing to abut on the continuous sheet, and a tension increasing mechanism disposed on the upstream side of the pre−centering mechanism in the normal direction and increasing the tension of the sheet.
