Abstract
A conveying apparatus includes a first pair of rollers having a drive roller and a pinch roller driven by the drive roller, a second pair of rollers provided downstream of the first pair of rollers, and an arm member supporting the drive roller and adapted to be swingable such that a force for pressing the drive roller against the pinch roller increases as a conveyance resistance of the sheet increases. The force for pressing the drive roller against the pinch roller decreases if driven by the moving sheet. The conveying speed of the second pair of rollers is set to be higher than the conveying speed of the drive roller so as to cause the drive roller to be driven by the sheet in the case where a skew of the sheet has been corrected and the sheet having the skew corrected is conveyed by the second pair of rollers.
