摘要： A sheet feeder, which is included in an image forming apparatus, includes a sheet loader on which a sheet is loaded, a sheet feeding body to feed the sheet from the sheet loader, and a sheet separator disposed to contact the sheet feeding body. The sheet is fed at a first average sheet feeding speed at which the sheet feeding body is in contact with the sheet separator without holding the sheet with the sheet separator. The sheet is fed at a second average sheet feeding speed at which the sheet feeding body is holding the sheet with the sheet separator. The first average sheet feeding speed is set smaller than the second average sheet feeding speed.

摘要： A feeding device includes a paper feed tray, a detector on an image forming apparatus main body, a control member rotatably supported by the paper feed tray, and spacers. The detector includes movable pieces and contact points corresponding to the movable piece, and switches each contact point by the position of the corresponding movable piece. The control member includes a control surface formed on its outer circumferential surface with projecting and recessed portions. The projecting and recessed portions are disposed in a pattern corresponding to rotation angles in an area of the control surface facing the movable pieces. Controlling the positions of the movable pieces according to the pattern encodes paper size. Each movable piece is lined in the circumferential direction facing the control surface. The outer circumferential surface of the projecting portions is formed in a cylindrical surface shape centering around the rotational axis of the control member.
