Abstract
A sheet feeding apparatus includes a controller for shifting a sheet attractor from a stand-by state in which the attractor is away from a sheet accommodated in a sheet stacking device to an attraction state in which the attractor is elastically deformed to surface-contact with the sheet stacked on the stacker to electrostatically attract the sheet, to a separating state for separating the sheet from a lower sheet by lifting a downstream end of the sheet with respect to the feeding direction, and to a spaced state in which the attractor spaces the attracted sheet from the lower sheet, the controller changing a slackness of the attractor in the separating state on the basis of a stiffness information of the sheet.
