A sheet processing apparatus comprising:
- a blade having a plurality of teeth aligned in a row;
- a mover to move along a direction in which the plurality of teeth are aligned and form a perforation in a sheet sandwiched between the blade and the mover, the mover including a groove at a position opposite the blade;
- and
- a pressure device to press the mover toward the blade.
