<p>A sheet feeding unit that can be incorporated in an image forming apparatus includes an endless belt and a charging member. The charging member may charge the endless belt with an alternating voltage to attract a sheet to separate from multiple sheets and feed the sheet, and may have an electrode contacting the endless belt at an angle thereto and between which a nip is formed. The endless belt and an interior surface of the charging member may define a space across which electric discharge is performed to charge an outer layer of the endless belt. A distance of the gap and a length of the nip in the sheet conveyance direction may define a basic charging region. The distance of the basic charging region may be smaller than a distance of a unit charging region where the electric charge of identical polarity is held on the endless belt.</p> |
