Abstract: An image forming apparatus of the invention includes an image forming unit configured to form an image on a sheet; a plurality of storage portions each configured to store the sheet with the image formed thereon by the image forming unit; an opening configured to expose the sheet stored in the storage portion to the outside; and a sheet moving unit configured to move the sheet until a leading edge of the sheet stored in the storage portion passes the opening and a portion of the sheet is exposed from the opening to the outside. The sheet moving unit exposes sheets stored in a plurality of the storage portions in a stacked manner from the opening.
