Patent ID: 8342522

Claim:
A sheet conveyance apparatus comprising: a conveyance unit configured to convey a sheet; and a pair of roller units provided on a downstream of the conveyance unit in a conveyance direction, wherein one roller unit of the pair of roller units is a drive roller, and the other roller unit of the pair of roller units includes a plurality of driven rollers each pressurized against the drive roller, wherein the pair of roller units forms a plurality of nipping portions, arranged along a width direction orthogonal to the conveyance direction, for nipping and thereby conveying the sheet, in a state that a rotation of the pair of roller is stopped, a downstream end of the sheet to be conveyed is caused to abut against abutting positions of the plurality of nipping portion to correct a skew of the sheet, and wherein the driven rollers nearer to a center in the width direction have a smaller diameter than the driven rollers at both end sides in the width direction so that the abutting position of the nipping portion nearer to a center in the width direction is positioned on a more downstream in the conveyance direction than the abutting position of the nipping portion at end side in the width direction.
