摘要：
A sheet conveying device includes entrance rollers and registration rollers. The entrance rollers convey a sheet received from delivery rollers to the registration rollers. The registration rollers correct skew of the sheet. A conveying path between the delivery rollers and the registration rollers is equal to or slightly longer than a length of a sheet in a maximum allowable size for skew correction in a conveying direction in which the sheet is conveyed on the conveying path.
