Sheet bundle binding processing apparatus and image forming system having the same

A sheet bundle binding processing apparatus, comprising:

• a stack portion on which sheets are stacked;
• a press binding device which binds sheets stacked on the stack portion by deforming the sheets;
• a first taking-off device which applies a taking-off force to sheets bound by the press binding device for taking off the sheets from the press binding device;
• and
• a second taking-off device which applies a taking-off force to an edge of sheets bound by the press binding device for taking off the sheets from the press binding device,
• wherein the first taking-off device is configured to be a member different from the second taking-off device.
