An image reading apparatus which is capable of performing a stable reading operation and matching a sub-scanning magnification with which an original image is scanned, between the front side of an original and the reverse side of the same. A CCD line sensor reads the front side of an original, and a CIS line sensor reads the reverse side of the same. A lead roller is disposed upstream of the CCD line sensor and conveys the original at a first conveying speed. A discharge roller is disposed downstream of the CCD line sensor and conveys the original at a second conveying speed which is higher than the first conveying speed. A CPU controls one main scanning time period of the CCD line sensor after the original is held by the discharge roller, such that the one main scanning time period becomes shorter than before the original is held by the discharge roller.
