More Information
Summary:A fixing device includes a belt member, an inner circumferential rotating body, an outer circumferential rotating body, and a rotation starter. The belt member has an inner circumferential surface and an outer circumferential surface and fixes an image formed on a recording medium. The inner circumferential surface of the belt member is looped over the inner circumferential rotating body. The inner circumferential rotating body rotates the belt member. The outer circumferential rotating body is movable between a contact position at which the outer circumferential rotating body is in contact with the outer circumferential surface of the belt member and a separated position at which the outer circumferential rotating body is separated from the outer circumferential surface of the belt member. The outer circumferential rotating body rotates the belt member when the outer circumferential rotating body is disposed at the contact position. The rotation starter moves the outer circumferential rotating body toward the separated position and rotates the belt member by using the inner circumferential rotating body after the rotation starter has rotated the belt member by using the outer circumferential rotating body disposed at the contact position when the belt member is started to be rotated.
