PROBLEM TO BE SOLVED: To facilitate supplying of sheets without mistaking the sheet type when sheet supplying is required in a sheet feed tray. SOLUTION: The sheet feeding device includes a plurality of sheet feed trays in which sheets are stored, a sheet feeding section which enables a continuous sheet feeding of sheets stored in the sheet feed tray, and a control section which controls the sheet feeding section and has an auto tray switch function, and the control section obtains information on an amount of sheets stored in the sheet feed tray, during a continuous sheet feeding from the sheet feed tray, and determines whether or not the amount of the remaining sheets in the sheet feed tray satisfies the prescribed condition. In the case where the prescribed condition is satisfied, the control section stops motion of sheet feeding from the sheet feed tray while leaving sheets in the sheet feed tray. When the auto tray function is effective, the control section stops motion of sheet feeding from the sheet feed tray and starts motion of sheet feeding from another sheet feed tray having the same set sheet information to continue continuous sheet feeding, so that without stopping the device, observation using the remaining sheets is made possible, and confirmation of the remaining sheets is made possible without losing productivity.
