Abstract
An image reading apparatus capable of detecting correct color tones of an image printed on a sheet is described. The image reading apparatus includes a scanner, a colorimeter, a cooling device, a temperature control unit, and an image correction unit. While an image correction process is not performed, the temperature control unitcontrols the cooling temperature to a first temperature for shifting the cooling deviceto a predetermined cooled state. While the image correction process is performed, the temperature control unitcontrols the cooling temperature to a second temperature for making the temperature of the sheet uniform. The image correction unitobtains, while the temperature control unitcontrols the cooling temperature to the second temperature, the correction amount of the image based on the colorimetric measurement result of the colorimeterand the reading result of the scanner
