<p><P>PROBLEM TO BE SOLVED: To provide a sheet treatment device and an image forming device, capable of bundle-conveying a bundle of sheets stacked on a tray without buckling by their own weight regardless of the thickness and the number of sheets. <P>SOLUTION: The sheet treatment device includes: a storage guide 803 for stacking the conveyed sheets; a projecting member 830 for selectively performing treatment relative to the bundle of sheets comprising a plurality of sheets stacked on the storage guide 803 at a predetermined treatment position; a pair of folding rollers 810; an end stopper 805 for grasping the bundle of sheets stacked on the storage guide 803 and moving them to the treatment position; and feeding rollers 806, 807 capable of moving the bundle of sheets stacked on the storage guide 803 to an abutment position for pressing the bundle of sheets to the storage guide 803 and a retreating position for releasing the pressing of the bundle of sheets. The feeding rollers 806, 807 presses the bundle of sheets grasped by the end stopper 805 and moved to the treatment position, to the storage guide 803 on an upstream side in a movement direction of the bundle of sheets by the end stopper 805. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
