Title: Image heating apparatus

Abstract: An image heating apparatus includes an endless belt; first, second, third and fourth resistors having resistances R1, R2, R3 and R4, arranged in this order from an upstream side in a feeding direction of the recording material, and R1=R2 and R3=R4. The connection state of the resistors is switchable between a first state in which the first and second resistors are connected in parallel, the third and fourth resistors are connected in parallel, and a set of the first and second resistors and a set of the third and fourth resistors are connected in parallel, and a second state in which the first resistor second resistors are connected in series, the third and fourth resistors are connected in series, and a set of the first and second resistors and a set of the third and fourth resistors are connected in parallel.
