PROBLEM TO BE SOLVED: To make it possible to solve problems of complication of a mechanism and control and noise, to reduce binding process time, and deal with demand of acceleration in a sheet post-processing device for performing a binding process with toner used as an adhesive.SOLUTION: A toner image 48 serving as an adhesive is formed in a binding margin, and a sheet P having been fixed by a fixing device of an image formation apparatus is stacked in a stack tray 34 of a sheet post-processing device. During stacking, the binding margin of the sheet P is heated by a receiving-side heat source 44 of preheating means 45. After a predetermined number of sheets P are stacked, pressurizing means 50 is driven to pressure-contact a pressing-side rubber pad 62 heated by a heating-side heat source 60 with the binding margin. A sheet bundle is discharged by a transport roller 36. |
