A sheet-stapling apparatus (1A) mounts a center-fold booklet (20) and staples the booklet at a fold (10a) of the booklet by a staple. The sheet-stapling apparatus has a supporting member (2) that mounts the center-fold booklet, pushing members (3, 3) that push the booklet to the supporting member, a stapler (4) that penetrates the staple through the booklet and a clincher (5) that clinches legs of the staple to bind the booklet. Each pushing member (3) has a pushing recess portion (30) for pushing the fold of the booklet. The pushing recess portion spreads from a booklet-positioning angle (±2) to a booklet-pushing angle (±3) to prevent the booklet from shifting. |
