A sheet feeding cassette is capable of being mounted to and removed from an apparatus body along a specified mounting direction. The sheet accommodated within a sheet accommodating portion is conveyed through a sheet conveyance path in a sheet conveyance direction extending along the mounting direction. A sheet feeding roller is disposed at an inlet side of the sheet conveyance path so as to face the sheet accommodating portion. A retard roller is disposed so as to face the sheet feeding roller. The sheet feeding roller forms a sheet feeding nip between the sheet feeding roller and the retard roller. A lock mechanism locks drawing-out of the sheet feeding cassette from the apparatus body or releases the lock. A separator moves the retard roller away from the sheet feeding roller prior to or simultaneously with the lock being released by the lock mechanism. |
