SHEET CONVEYING DEVICE AND IMAGE FORMING APPARATUS WITH THE SAME

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).

主权项

1. A sheet conveying device comprising:
a plurality of first conveyance rollers; a plurality of second conveyance rollers that face the respective plurality of first conveyance rollers, the plurality of second conveyance rollers being configured to convey a sheet while sandwiching the sheet between the second conveyance rollers and the first conveyance rollers to be rotated; and a stiffening roller disposed coaxially with either or both of the first and second conveyance rollers, the stiffening roller having a diameter larger than a diameter of either or both of the first and second conveyance rollers, wherein the stiffening roller includes a first stiffening roller and a second stiffening roller, the first stiffening roller being configured to integrally rotate with a conveyance roller, the second stiffening roller being configured to freely rotate with respect to a conveyance roller.
