Abstract
In a sheet feeding device, when a leading end of a recording sheet is guided to a nip region along a leading end portion of a sheet guide member in contact with a surface of a separation roller, the leading end of the recording sheet slides and moves on surfaces of projected end portions to be guided to the vicinity of the nip region, and the leading end of the recording sheet passes through the nip region quickly. Hence, a sheet feed error is much less likely to occur. Since a distance from recessed end portions to the nip region is longer and the leading end of the recording sheet is in contact with the separation roller for a longer time right after passing the recessed end portions until reaching the nip region, even though a plurality of recording sheets is stacked, the recording sheets are separated one by one by the separation roller, preventing a multi-sheet feed of the sheets.
