A sheet feeding apparatus includes a back end detecting sensor which detects a back end side in a conveying direction of the topmost sheet stacked on the sheet tray, a front end detecting sensor which detects a front end side in the conveying direction of the topmost sheet, and a CPU. The CPU disables start of a sheet feeding operation of a feeding unit in a case where the back end detecting sensor and the front end detecting sensor do not detect the sheet when the sheet tray is lifted toward the feeding unit and then stopped in a predetermined position. Accordingly, a state that a feeding failure is possibly caused is detected before feeding the sheets so as to eliminate the wasteful feeding operation. |
