This present invention provides an image reading apparatus aiming at improving its operability while saving the cost and an image forming apparatus provided with the same. Sponges for pressing a pressing plate against a platen glass are constituted of nine sponges. Then, restoration forces Fa to Fc generated when sponges on a front side of a document feeding apparatus far from a fulcrum shaft of a hinge unit are crushed are set smaller than restoration forces Fg to Fi generated when sponges on a deep side of the document feeding apparatus near the fulcrum shaft 45 of the hinge unit are crushed.
