Provided is an image heating device wherein occurrences of failure of electrical power supply to a belt are suppressed. An image heating device has the following: a fusing belt (100) provided with a heating layer (102); a pressure roller (110) that rotatably drives the belt; an electric power supply ring (119) provided along the outer peripheral surface of the fusing belt at one end side of the fusing belt in the longitudinal direction and electrically connected with the heating layer; brushes (81) in contact with the outer peripheral surface of the electric power supply ring and electrically connected with the electric power supply ring; a power supply circuit (79) for supplying power to the brushes; and plate springs, which are plate springs (82) elastically pressing the brushes toward the electric power supply ring, for making contact with the electric power supply ring when the brushes have been worn down a prescribed amount. |
