Abstract
A heating device includes a support member including a support face, a first heating unit heating the support face, a second heating unit heating the support face, and a control unit independently controlling an output of the first heating unit and an output of the second heating unit. A second heated region is positioned adjacent to a first heated region. The first heating unit and the second heating unit are arranged, in order, from a center, in the width direction, of the support face toward an end thereof. A second detection unit detecting a temperature of the support face is provided in the second heated region, at a location further to an opposite side from the first heating unit than a center, in the width direction, of the second heated region. The control unit controls an output of the second heating unit based on detection of the second detection unit.
