Abstract
A backup roller is formed by a member having a rotational axis and a circumferential region around which a plurality of teeth are arranged. Each tooth of the plurality of teeth has a tip end extending in a direction away from the rotational axis. When the backup roller is rotated the tip end of each of the plurality of teeth sequentially extends toward the rotational axis of a drive roller at an angle non-orthogonal to the rotational axis of the drive roller.
