Abstract
A sheet feeder includes a first rotary member, a separation member that cooperates with the first rotary member in holding the sheet between the separation member and the first rotary member to define a separation nip, a conveyance unit disposed downstream of the separation nip in a conveyance direction of the sheet, a driving unit, and a control unit. The first rotary member feeds a sheet. The conveyance unit conveys the sheet. The driving unit drives the first rotary member. The control unit controls the driving unit to stop driving the first rotary member when a leading edge of the sheet reaches the conveyance unit, and controls the driving unit to restart driving the first rotary member when a trailing edge portion of the sheet comes out of the separation nip.
