Abstract:
1. An image heating apparatus comprising: a first heat generation member that heats up by power supplied from a commercial power supply, the first heat generation member being connected between a first connector and a second connector; a second heat generation member that heats up by power supplied from the commercial power supply, the second heat generation member beings connected between the second connector and a third connector; a drive element that controls power supplied to the first heat generation member and the second heat generation member; a connection state switching section that switches the first heat generation member and the second heat generation member between a serial connection state and a parallel connection state, the connection state switching section including a make contact relay or a break contact relay having a first contact connected to a first power terminal of the commercial power supply and a second contact connected to the second connector, and a transfer-contact relay having a common contact connected the first connector, a first contact connected to the first power terminal side of the commercial power supply and a second contact connected to the drive element; wherein a power supply path extending from the first power terminal of the commercial power supply is branched off into the first contact of the make contact relay or the break contact relay and the first contact of the transfer-contact relay, wherein the power supply path extending from the second power terminal of the commercial power supply is branched off into the second contact of the transfer relay and the third connector through the drive element, and a capacitor connected between a circuit line of the power supply path between the second contact of the make contact relay or the break contact relay and the second connector and the second power terminal of the commercial power supply.
