Abstract
An image reading device includes an image sensor, a color reference portion, a test control portion, a standard distribution information storage portion, a type determination portion, and an abnormality notification portion. The image sensor is capable of outputting detection data of an amount of received light from each of a plurality of partial scanning areas, each at an individual channel. The test control portion is configured to cause the image sensor to operate under a plurality of test operation conditions different in resolution, when a document is not present. If a distribution state of the detection data at each channel acquired under each test operation condition does not match any of standard distribution information, the abnormality notification portion notifies an abnormality of another device related to the image sensor. The standard distribution information represents a standard distribution state of data at each channel under each test operation condition.
