An image forming apparatus includes an image forming apparatus body, a cassette attaching section and a media cassette. The media cassette includes a loading plate, a pushing up member, a projecting portion and a plate holding portion that engages the loading plate. A release portion engages the plate holding portion. The cassette attaching section has a media supplying roller that supplies media to the image forming apparatus body. The plate holding portion engages the loading plate and holds the loading plate against a pushing up force of the pushing up member. The plate holding portion holds the loading plate when the support section of the media cassette is located outside the cassette attaching section. The media cassette may be inserted into the cassette attaching section.
