Abstract
A heating device includes first and second heat generating members, and first and second thermistors. A controller is capable of switching the heating device to a first mode in which the temperature of the first heat generating member is controlled based on the detecting result of the first thermistor and the temperature of the second heat generating member is controlled depending on control of the first heat generating member, and a second mode in which the temperature of the first heat generating member is controlled based on the detecting result of the first thermistor and the temperature of the second heat generating member is independently controlled based on the detecting result of the second thermistor. The controller switches to the first mode during the recording material is passing through a nip portion, and switches to the second mode during the recording material is not passing through the nip portion.
