Abstract:
1. A sheet post-processing apparatus comprising: a processing tray that aligns stacked one or plural sheets; a stacking tray on which the sheet(s) aligned by the processing tray is stacked; a conveying mechanism that conveys the sheet(s) aligned by the processing tray to the stacking tray; a pushing member, a distal end of which is located at an end on the stacking tray side of the processing tray, the pushing member being arranged to allow the distal end to project in a direction of the stacking tray; a pushing member driving mechanism that reciprocatingly drives the pushing member such that the distal end projects in the direction of the stacking tray and returns to the processing tray side after the projection; and a driving control mechanism that controls to drive the pushing member driving mechanism to perform a reciprocating operation for projecting, in a process of conveying the sheet(s) from the processing tray to the stacking tray with the conveying mechanism, the distal end of the pushing member to the stacking tray side to push a lower surface of the sheet(s) and returning the distal end to the processing tray side after the pushing, wherein the pushing member includes a frictional member at the distal end that pushes the lower surface of the sheet(s).
