ABSTRACT:
A sheet post-processing apparatus is constructed to apply post-processing to sheets successively supplied from an image forming apparatus and received into an apparatus main body, and includes a main discharge tray onto which the sheets that have passed through the apparatus main body are discharged. The sheet post-processing apparatus further has an elevating mechanism for moving the main discharge tray up and down and a control unit for controlling an elevation control of the elevating mechanism. The control unit controls the elevating mechanism to move the main discharge tray up and down in synchronism with the discharge of the sheet onto the main discharge tray. The control unit carries out the elevation control of the main discharge tray so as not to adversely affect the discharge of a succeeding sheet even if the sheet discharged from the apparatus main body is curled up or down.
