摘要：
In a sheet discharging unit including a pair of sheet discharge rollers which discharges a sheet P, the outer diameter of a sheet discharge drive roller included in the pair of sheet discharge rollers is set so that the outer diameter of a straight portion which is a central portion in the width direction perpendicular to the discharging direction of the sheet P is larger than the outer diameters of both end portions in the width direction. Further, in the sheet discharging unit, the pair of sheet discharge rollers respectively include metal shafts extending in the width direction and elastic layers respectively wound around the metal shafts and continuously formed to be longer in the width direction than the width of a sheet P with a passable maximum size. Further, at least one elastic layer of the pair of sheet discharge rollers is formed of a foamed material.
