Rotation device, fixing device, and image forming apparatus

Abstract

A rotation device includes: a first rotator that includes a recessed portion formed on an outer circumferential surface and that is rotatable in a predetermined rotation direction; a second rotator that comes into contact with a portion of the outer circumferential surface in a range from an upstream end to a downstream end of the recessed portion in the rotation direction and that is separated from the first rotator outward in a radial direction of the first rotator when the first rotator is in a position of rotation such that the recessed portion faces the second rotator; a first drive mechanism that rotates the first rotator or the second rotator and that causes the other of the first rotator or the second rotator to rotate in conjunction in a contact state in which the first rotator and the second rotator are in contact with each other; and a second drive mechanism that rotates the other in a separation state in which the first rotator and the second rotator are separated from each other.

Dependencies are inferred from the claim text.
