摘要： In a sheet conveyance device, a plurality of driving rollers opposes a plurality of driven rollers to form nip portions between the plurality of driving rollers and the plurality of driven rollers. A center portion of a driving shaft for supporting the plurality of driving rollers in an axial direction of the driving shaft is bent downstream in a sheet conveyance direction so that the plurality of driving rollers is shifted downstream in the sheet conveyance direction and tilted with respect to the sheet conveyance direction in a V-like shape about a center line in a width direction of a sheet. The plurality of driven rollers is shifted downstream in the sheet conveyance direction by an amount determined by an amount by which the plurality of driving rollers is shifted downstream in the sheet conveyance direction.
