摘要：
A sheet processing apparatus includes: a buffer unit which stores plural supplied sheets with upstream edges in a conveying direction thereof aligned; a processing tray on which sheets discharged from the buffer unit are stacked; and an oscillation roller pair and a return roller which convey the sheet stacked on the processing tray to bring the sheet into abutment against a stopper for receiving the upstream edge of the sheet. The buffer unit is adapted to align the upstream edges of only sheets to be stored before a sheet to be supplied last among the sheets to be stored.
