A sheet feeding apparatus includes a sheet feeding tray, a lock mechanism that locks the sheet feeding tray, a sheet feeding unit that feeds sheets from the sheet feeding tray one by one, an opening and closing unit that opens and closes a conveyance path, a sheet detecting sensor that detects presence of a sheet at a position at which the opening and closing unit is arranged, and a state detecting unit that detects a state of the opening and closing unit. When the sheet detecting sensor detects that a sheet is stuck during conveyance of the sheet, the lock mechanism locks the sheet feeding tray not to be drawn out, and unlock the sheet feeding tray after the opening and closing unit opens the conveyance path.
