Abstract
A sheet conveying device includes a sheet skew corrector to correct a skew of a leading end of a sheet inclining from a sheet conveyance direction and a pair of registration rollers disposed upstream of the sheet skew corrector in the sheet conveyance direction. The pair of registration rollers freely contacts and separates from each other. The pair of registration rollers conveys the sheet downstream of the sheet skew corrector in the sheet conveyance direction when driven at a prescribed time. A pair of conveyance rollers is placed upstream of the pair of registration rollers in the sheet conveyance direction. The pair of conveyance rollers continuously sandwiches the sheet from when the sheet with the skew corrected is sandwiched by the pair of registration rollers to when a trailing end of the sheet passes between the pair of conveyance rollers.
