A movable sheet separating unit is pushed all the time by a lifting spring in a direction toward a feeding roller. In a non-feeding state, a sheet lifting plate is engaged with an operating fraction so that the movable sheet separating unit is held in a standby position where a separating pad is separated from the feeding roller. In a feeding state, the sheet lifting plate rises and disengages from the operating fraction so that the movable sheets separating unit moves to a pressing position where the separating pad is pressed against the feeding roller. In the pressing position, the separating pad is pressed against the feeding roller via a rotatable support base by a pressing spring, and is displaced by rotation in a direction away from the feeding roller in accordance with a thickness of a sheet S passing through between the separating pad and the feeding roller. Thus, durability of the separating pad can be improved, and a feeder suitable for a fixing type feeding cassette can be provided.
