Abstract
A deviation detection device to detect a deviation of a rotator includes a contact member disposed in contact with the rotator and configured to move, following a deviation of the rotator in a width direction of the rotator. The deviation detection device further includes a deviation detector configured to detect a direction of the deviation and a deviation amount of the rotator based on a displacement of the contact member, and a wear detector configured to detect a state in which an amount of wear of the contact member has reached a threshold.
