    摘要: A sheet conveying device (30) includes a plurality of first conveyance rollers (31) and a plurality of second conveyance rollers (32). The sheet conveying device (30) includes stiffening rollers (34). The stiffening rollers (34) are disposed coaxially with at least one conveyance rollers (32) among the first and second conveyance rollers (31) and (32), and have diameters larger than diameters of the conveyance rollers (32). The stiffening rollers (34) includes first stiffening rollers (34a), which apply conveying forces to a sheet (P), and second stiffening rollers (34b), which apply smaller conveying forces to the sheet (P) than the conveying forces to the sheet (P) in the first stiffening rollers (34a).
