Abstract
A sheet feeding device includes a sheet feeding member, a friction separation member, a retaining member, a downstream guiding member, and a biasing member. The downstream guiding member is arranged downstream of a sheet conveyance direction than the friction separation member such that its guide surface is inclined at a predetermined angle to a front surface of the friction separation member towards the sheet feeding member. A line joining an apex of a sheet guiding member arranged upstream of the sheet conveyance direction than the friction separation member and an apex of the downstream guiding unit is positioned towards the sheet feeding member than a contact portion of the sheet feeding member and the friction separation member.
