Abstract

See full text

The image heating apparatus includes first and heat generation member, a connection state switching section switching the first and second heat generation members between a serial connection state and a parallel connection state, the connection state switching section having a first make-or-break-contact relay and a second transfer-contact relay, a drive element provided used for controlling power supplied to the first and second heat generation members, and a capacitor between a power supply path closer to the side of the first and second heat generation members rather than the first relay and a power supply path closer to the commercial power supply side rather than the drive element. The image heating apparatus can suppress an increase in noise level of a noise terminal voltage by performing power control on the heater.
