Abstract
In a sheet post-processing apparatus that folds a sheet bundle, a folding roller drive motor that drives folding rollers is PWM driven such that its speed is varied in each control during the period until a blade contacts the sheet bundle, during the period when the sheet bundle is conveyed to a discharge port, during discharge operation, and during return of the motor to its home position.

A sheet post-processing apparatus comprising;
- stitching means for stitching with staples a sheet bundle conveyed along a conveyance path, the stitching means stitching the sheet bundle at plural places thereof along a straight line orthogonal to the conveyance direction;
- folding means including a pair of folding rollers disposed downstream of the stitching means on the conveyance path and a blade that pushes the sheet bundle into a contact portion of the pair of folding rollers;
- a folding roller drive motor that drives the pair of folding rollers;
- and
- control means for controlling the driving or stopping operation of the folding roller drive motor in correspondence to the process of folding the sheet bundle,
- wherein the control means varies the speed of the folding roller drive motor during the period until the blade contacts the sheet bundle, during the period when the sheet bundle after folding is conveyed to a discharge port, during discharge operation of the sheet bundle, and during return of the folding roller drive motor to its home position.
