Medium processing apparatus, image forming apparatus, and image forming system

Abstract

A medium processing apparatus includes a conveyor, a position changer, and circuitry. The conveyor conveys a sheet medium in a conveyance direction. The conveyor includes a roller pair having opposed rollers opposed to each other in a main scanning direction orthogonal to the conveyance direction. The roller pair nips an end portion of the sheet medium in the main scanning direction and convey the sheet medium in the conveyance direction. The position changer changes a position at which the roller pair nips the sheet medium to change an opposing distance between the opposed rollers of the roller pair in the main scanning direction. The circuitry is to control the conveyor and the position changer to change the opposing distance based on attribute information of the sheet medium.
