CURL CORRECTING DEVICE AND IMAGE FORMING APPARATUS INCLUDING THIS

摘要

A curl correcting device includes a pair of fixed guides and a change-over guide. The pair of fixed guides composes a curved part of a conveyance path. The change-over guide is provided to be contactable with a sheet from a radial outer side of the curved part. An outer guide includes a pair of side pressing parts and a bulge part. The pair of side pressing parts is formed at both ends in a width direction. The bulge part is formed between the pair of side pressing parts so as to bulge toward the radial outer side of the curved part. The change-over guide is configured to move to a first correcting position when the sheet curled along the conveyance direction is conveyed through the conveyance path and to move to a second correcting position when the sheet curled along the width direction is conveyed through the conveyance path.

主权项

1. A curl correcting device, comprising:
a pair of fixed guides composing a curved part of a conveyance path through which a sheet is conveyed while being curved; and a change-over guide provided to be contactable with the sheet conveyed through the conveyance path from a radial outer side of the curved part; wherein the pair of fixed guides includes an outer guide at the radial outer side of the curved part, the outer guide comprising: a pair of side pressing parts formed at both ends in a width direction orthogonal to a conveyance direction of the sheet; and a bulge part formed between the pair of side pressing parts so as to bulge toward the radial outer side of the curved part more than the pair of side pressing parts; and wherein the change-over guide is configured to move to a first correcting position set within the bulge part in a case where the sheet curled along the conveyance direction is conveyed through the conveyance path and to move to a second correcting position set at the radial outer side of the curved part more than the first correcting position in a case where the sheet curled along the width direction is conveyed through the conveyance path.
