A sheet stacking portion for stacking sheets is provided on a cover openably/closably supported on an apparatus body. The sheet stacking portion is guided between a first position and a second position along the cover by a guide portion. A sheet staked on the sheet stacking portion at the first position is fed via a sheet feeding portion. The sheet stacking portion is moved in conjunction with a cover closing action from the first position to the second position not interfering with the sheet feeding portion via a moving portion. A first end side of the moving portion is turnably supported on the apparatus body and a second end side is connected to the sheet stacking portion.
