Abstract
A sheet feeding device includes a stacker on which sheets are placed, a sheet feeding device for separating and feeding a sheet from other sheets on the stacker, a sheet overlap sensing device placed in a sheet conveying path at a downstream side of the sheet feeding device, and a sheet sensing device for detecting whether the sheet is located in the sheet overlap sensing device. An error determining device determines whether the sheet overlap sensing device is operating normally.
