To provide a sheet after-processing device capable of unifying the rising characteristic of a DC motor regardless of the number of sheets in a bundle of delivery sheets.
The number of sheets loaded on a processing tray 630 and fed out in bundle onto a stack tray 700, is counted (S1). Whether the number of sheets fed out in bundle is less than a predetermined value n or not is determined (S2). In a case when the number of sheets fed out in bundle is less than the predetermined value n, a CPU 556 determines a reference voltage value to a predetermined low voltage value (S4). On the other hand, when the number of sheets fed out in bundle is more than the predetermined value n, the reference voltage value is determined to a high voltage value (S3). After the determination of the reference voltage, a bundle delivery motor M4 is driven (S5) to feed out the bundle of sheets.
