ABSTRACT:
A sheet feeding apparatus having a sheet supporting tray for supporting sheets, a sheet supply roller for feeding out the sheet supported by the sheet supporting tray thereon, a separating device having a plurality of separating surfaces of different coefficients of friction and adapted to separate the sheets one by one by cooperating with the sheet supply and roller by abutting against the sheet supply roller, a separating surface changing device for changing the separating surface to be abutted against the sheet supply tray, a detector for detecting a poor separating condition in which the sheets are not readily separated one by one by the separating tray, and a controller for controlling the separating surface changing device in accordance with the detected result of the detector to change the separating surface to be abutted against the sheet supply tray.
