The present invention provides an image reading apparatus capable of detecting deformation of a manuscript prior to formation of blocking and capable of inhibiting damaging generated on the manuscript. The image reading apparatus includes feeding rollers configured to come into contact with the lowermost medium of media mounted on a medium mounting section and transport the medium toward a downstream side, separation rollers configured to nip and separate the medium with the feeding rollers therebetween, and a medium detection section configured to detect the medium at a detection position closer to an edge side of the medium than the nip positions of the feeding rollers and the separation rollers in the medium width direction and the detection position overlapping one of the feeding rollers and the separation rollers in a side view of the medium transport path.
