发明名称 Sheet feeder and image forming apparatus having the same
摘要 A fixed separating plate, having a separating strip, is provided to a middle of a lower end portion of a sheet holder, which holds a plurality of sheets, in a sheet width direction. A pair of first and second movable separating plates are provided on each side of the fixed separating plate. The first and second movable separating plates are upwardly urged and can descend lower than the fixed separating plate. The first and second movable separating plates independently rotate downward when the first and second movable separating plates are pressed by leading edges of the sheets that are subjected to a sheet feeding force from the sheet feed roller. With this structure, the degree of the inclined angles of the movable separating plates, which receive the leading edges of the side areas of the sheets to be fed, can be changed in accordance with the size and rigidity of the sheets stacked on the sheet holder.
