Abstract
A sheet feeder includes a feeding member to contact a sheet and feed the sheet downstream in a sheet conveyance direction, a friction pad disposed facing the feeding member to contact the feeding member, and a receiving table including a pad mount to hold a side of the friction pad opposite a nip between the friction pad and the feeding member. The friction pad includes a fixed range secured to the pad mount upstream from the nip and a movable range extending downstream the nip in the sheet conveyance direction. A first friction force of the pad mount to act on the movable range of the friction pad is smaller than a second friction force of the sheet to act on the movable range of the friction pad.
