ABSTRACT:
An image reader includes a first read unit, a second read unit independent of the first read unit, a determination unit, a storage unit, and a correction unit. The first read unit reads a first face of a fed document to create image data. The second read unit reads a second face of the fed document to create the image data. The determination unit determines the read unit that has read a recording face of a test chart when a test chart document, with a test chart recorded on one face, is read. The storage unit stores the read unit that has read the recording face of the test chart and sampling data extracted from image data created by the read unit that has read the recording face of the test chart in association with each other. The correction unit corrects read characteristics of the read unit associated with the sampling data, based on the sampling data.
