Abstract
An image reading apparatus according to the present invention includes: a conveyor which conveys an original in a first direction; a light transmitting member which is provided with coating in a first region of a surface facing the original; a reading unit which reads an image at a reading position of the original through the light transmitting member; and a controller which performs processing on the image and which changes the reading position by moving the reading unit when abnormality is detected in the processing. The coating includes a silicon-containing perfluoropolyether compound. An electrically-conductive member is provided in a second region located on the surface of the light transmitting member, upstream of the first region in a conveyance direction of the original. A contact angle of the coating at a position corresponding to the reading position in the first region is appropriately set.
