Abstract:
A sheet feeding device includes a sheet carrying unit, an attraction separation device electrostatically attracting and separating an uppermost sheet from a sheet stack and including multiple rollers, an endless dielectric belt stretched over the multiple rollers, and an elastic member provided inside a loop of the belt to cause the endless dielectric belt to contact the uppermost sheet, a sheet conveying device, and a lifting and lowering device. The lifting and lowering device lifts the sheet stack to a lift position at which the uppermost sheet contacts with the attraction separation device, and the attraction separation device stands by for a predetermined time to attract the uppermost sheet and starts to convey the uppermost sheet after the predetermined time elapses in a state in which the sheet stack remains at the lift position.
