PROBLEM TO BE SOLVED: To detect absence of sheets on a sheet supporting member without using a sheet end sensor and display this absence in a sheet feeding device sending out sheets loaded on the sheet supporting member one by one. SOLUTION: A paper feeding roller 2 is rotated by a roller rotation starting signal even after sending out the last sheet S3 on a sheet supporting member 1 for detecting absence of sheets when a predetermined time passes from this rotation starting time and a tip of a sheet is not detected by a sheet sensor 4.
