Abstract

An image reading apparatus includes an image reading section and a detection section. The image reading section includes at least two detection units, and performs a reading operation on an image. The at least two detection units have respective spectral characteristics which are different from each other. The detection section detects a condition of an irregularity on an image carrier by comparing a detection result of the image read by the image reading section with an output characteristic. The output characteristic is stored in advance and is a color component obtained from a value obtained by the image reading section reading a test image having a region in at least one color.
