Abstract
A sheet conveyed to a sheet stacking portion is conveyed in a direction opposite to a sheet conveyance direction by a returning roller to bring a trailing edge of the sheet into abutment against a reference wall and regulate a trailing edge position of the sheet. A pressure portion which presses the sheet to the reference wall is pivotably provided between the returning roller and the reference wall. The pressure portion presses the sheet conveyed by the returning roller to the reference wall while urging the sheet with a first urging force and, after the sheet comes into abutment against the reference wall, is urged by the urging unit to press the sheet, the trailing edge position of which is regulated by the reference wall, with a second urging force larger than the first urging force to hold the sheet.
