    摘要: To enable a bunch of sheets to be reliably discharged to a stack tray, also in the case where weight of the bunch of sheets formed on a processing tray is large, a post-processing control section receives information on an ink discharge amount, the number of sheets, sheet type, and printing mode (two-side/one-side) in printing on sheets from a main body control section of an image forming unit A, in forming a bunch of sheets on the processing tray. The control section thereby recognizes weight of a bunch of sheets formed on the processing tray, and when the section determines that the weight is heavier than predetermined weight, decreases a rotation velocity of a drive motor of a sheet bunch transport means, or increases a current amount applied to the drive motor. By this means, torque of the motor is increased, and the bunch of sheets is reliably discharged to the first stack tray.

    摘要: A post-processing apparatus includes a sheet carry-in path along which sheets from a carry-in port are fed through a sheet discharging port to a downstream post-processing position, and a collecting guide, for setting and collecting the sheets into a bunch. The collecting guide is located downstream of the sheet discharging port with a difference in level between the sheet discharging port and the collecting guide, is provided. A post-processing apparatus is provided for executing a stapling process and/or a folding process on the sheet bunch collected on the collecting guide. A sheet leading end regulating device is provided for regulating a position of leading ends of the sheets collected on the collecting guide device. The sheet leading end regulating device is movable according to a sheet size so that trailing ends of the sheet ends are placed at a predetermined position below the sheet discharging port.
