Abstract
An image heating device includes a rotator, a heater including a heat generating resistor, a connector electrically connected to the heater, and a power interrupting unit that detects an abnormal temperature rise of the heater and interrupt supply of the power to the heater. The power interrupting unit includes a first terminal and a second terminal, a first conductive sheet metal that electrically connects the connector to the first terminal, a second conductive sheet metal that to electrically connects the connector to the second terminal via the heat generating resistor, a length of the second conductive sheet metal being different from a length of the first conductive sheet metal in the longitudinal direction of the heater, and a supporting member supporting the heater and including a regulation portion that regulates rotation of the power interrupting unit.
