Abstract
A sheet feeding device incorporable in an image forming apparatus includes a sheet holder to hold a stack of sheets including an uppermost sheet, an endless belt, a charging member, a belt supporting unit including a drive roller and a driven roller, a moving mechanism to move the sheet holder, and a controller. The controller alternately controls the moving mechanism to move the sheet holder to a proximal position, the endless belt to contact the uppermost sheet held on the sheet holder, and the driven roller to rotate about the drive roller, to attract the uppermost sheet, and controls the moving mechanism to move the sheet holder to a distal position, the driven roller to rotate about the drive roller, and the endless belt to incline at a predetermined angle of separation, to separate the uppermost sheet from the multiple sheets.
