Abstract
A sheet processing apparatus includes an endless belt configured to convey the sheet by coming in contact with an upper surface of the sheet stacked on the sheet stacking portion, a shaft extending in a direction orthogonal to the sheet conveying direction, and a supporting portion rotatably supporting the drive rotating member and supporting the endless belt through the drive rotating member. The supporting portion is configured to be swingable about the shaft and the endless belt is raised and lowered by the supporting portion being swung by a lifting portion.
