A pair of edge guides provided on a medium mounting section of a medium feeding apparatus each include a volume limiter spaced from the mounting surface of the medium mounting section and extending from the guide surface of at least one of the pair of edge guides in a direction intersecting the guide surface, the volume limiter including a limiting surface that limits a number of sheets mounted on the medium mounting section. The limiting surface includes a groove extending in the feed direction, at a position between a corner portion formed at an intersection of an end portion of the limiting surface in the width direction and the guide surface, and the other end portion of the limiting surface, and configured to insert at least a part of a side edge of the medium, to thereby restrict the side edge from moving in the width direction.
