Abstract
A reading device, an image forming apparatus, and a method of correction. The reading device includes a scanner configured to read an image in a first wavelength range and an image in a second wavelength range from light reflected by a surface of a recording medium, a detector configured to detect a change from a reference position in a reading-depth direction when the surface of the recording medium is read by the scanner, based on an amount of characteristic read from the image in the second wavelength range, and a corrector configured to correct the image in the first wavelength range based on the change detected by the detector. The image forming apparatus includes the reading device, and an image forming device configured to form an image corrected by the corrector of the reading device on a recording medium. The method includes reading the image in the first wavelength.
