Abstract
A sheet finisher of the present invention is included in an image forming system and folds a stack of sheets sequentially transferred from an image forming apparatus thereto. The sheet finisher includes a fold roller pair for holding the stack of sheets being conveyed via a nip thereof. A reinforce roller reinforces the fold of the folded sheet stack in cooperation with a guide plate. A drive mechanism causes the reinforce roller to move in a direction perpendicular to a direction of sheet conveyance. A shock absorbing member is located at a position where the reinforce roller and guide plate contact each other.
