According to one embodiment, a sheet processing device includes a folding unit and a fold-enhancing unit. The folding unit folds a sheet and thus forms a fold line thereon. The fold-enhancing unit includes a fold-enhancing roller, an opposite member, and an auxiliary roller. The fold-enhancing roller moves along a fold-line direction in which the fold line on the sheet formed by the folding unit extends. The opposite member sandwiches the fold line with the fold-enhancing roller. The auxiliary roller rolls over the sheet from the same side as the fold-enhancing roller. The auxiliary roller is displaced in a unified manner with the fold-enhancing roller in the fold-line direction and the direction of the thickness of the folded sheet. A drag torque generated by the movement of the fold-enhancing roller in the fold-line direction is higher in the auxiliary roller than in the fold-enhancing roller.
