Abstract: A sheet feeding device includes an attracting mechanism and a changing mechanism. The attracting mechanism includes a lifting section and a maintaining section. The lifting section attracts a portion of a sheet material that is fed and lifts the portion of the sheet material. The maintaining section attracts an edge of the sheet material that is lifted by the lifting section and maintains an orientation of the edge of the sheet material. The changing mechanism changes at least one of an attraction force that is generated at the lifting section and an attraction force that is generated at the maintaining section.
