1. A sheet stacker comprising:
a sheet stacking portion on which a bundle of sheets is stacked in a stacking direction, the sheet stacking portion configured to move in the stacking direction;
a pair of sheet restrictors configured to move in a width direction of the bundle of sheets orthogonal to the stacking direction to regulate a position of the bundle of sheets in the width direction;
a sheet feeder configured to feed a top sheet of the bundle of sheets at a sheet feeding position in a sheet feeding direction orthogonal to the stacking direction and the width direction, the sheet feeding position at a top of the bundle of sheets in the stacking direction;
a position detector between the pair of sheet restrictors in the width direction and above the sheet feeding position in the stacking direction, the position detector configured to detect a position of the pair of sheet restrictors in the width direction; and
a stay at a center of the pair of sheet restrictors in the width direction and above the sheet feeding position, wherein the position detector is attached to the stay.
