摘要: A sheet post-processing apparatus includes an output tray on which a sheet ejected from a sheet outlet is stacked; a wall disposed downstream from the output tray in a sheet ejection direction; and an alignment member configured to contact and move the sheet on the output tray, to bring a rear end of the sheet in the sheet ejection direction into contact with the wall for alignment. The alignment member is selectively set at three positions of: an alignment position protruding beyond the wall toward the output tray to contact the sheet on the output tray; a withdrawn position inward of the wall; and a home position between the alignment position and the withdrawn position.

摘要: A sheet post-processing apparatus includes: a sheet stack tray; a rear-end-position regulating member, against which a rear end of the sheet on the tray is butted to align a position of the sheet in a sheet conveying direction to the stack tray, the rear end of the sheet being a rear end in the conveying direction; and a roller member that comes in contact with an upper surface of the sheet conveyed to an upper side of the tray, before the sheet is stacked on a stacking surface on the tray, and conveys the sheet stacked on the stacking surface toward the rear-end-position regulating member, wherein a rotation speed before stacking is set to be smaller than a rotation speed after stacking, and the rotation speed of before stacking is greater than zero.
