1. An inkjet printing apparatus comprising:
a conveyance section that conveys a cut sheet;
an ink ejection section that ejects an ink to form an image when the sheet passes a predetermined position;
a first heat source that is provided on a downstream side of the ink ejection section and dries an ink ejection face of the sheet; and
a second heat source that is arranged to face the first heat source and comes into contact with a back surface of the sheet opposite to the ink ejection face to heat the sheet,
a controller that controls an amount of heat applied to the sheet by each of the first heat source and the second heat source,
wherein, when the ink is ejected onto the second surface during double-sided printing, the controller reduces the amount of heat of each of the first heat source and the second heat source,
wherein the first heat source emits an electromagnetic wave to heat the ink ejection face by radiant heat.
