Abstract: An image reading apparatus includes a conveyance unit, a first reading unit, a first guide portion, a second reading unit, and a second guide portion. The second reading unit includes a rectangular transparent member, an optical reading unit, a housing, a first and a second contact portions, a first and a second pressing members, and a protruding portion. The first and the second contact portions are protruding from a facing surface of the housing. The protruding portion, when viewed from an upstream side in a conveyance direction of a recording material passing through a conveyance path between the second reading unit and the second guide portion, is disposed between the first contact portion and the second contact portion and protruding from the facing surface of the housing, a protruding amount of the protruding portion being smaller than protruding amounts of the first and the second contact portions.
