Rotation apparatus, fixing apparatus, and image forming apparatus

A rotation apparatus comprising:

• a first rotating body rotatable in a predetermined rotation direction;
• a second rotating body movable to a contact position at which the second rotating body comes into contact with an outer circumferential surface of the first rotating body and a separation position at which the second rotating body is separated from the first rotating body outward in a radial direction of the first rotating body and rotatable in a reverse direction to the rotation direction;
• a first drive mechanism that rotationally drives the first rotating body at a first circumferential speed and subordinately rotates the second rotating body at the contact position;
• and
• a second drive mechanism that generates a driving force in the reverse direction with respect to the second rotating body at the contact position and the separation position, rotationally drives the second rotating body at a second circumferential speed lower than the first circumferential speed at the separation position, and applies a resistance force in the reverse direction to the first rotating body via the second rotating body at the contact position.
