Abstract:
1. A conveying apparatus which conveys a sheet along a conveying path, the conveying apparatus comprising: a first pair of rollers which has a drive roller and a pinch roller driven by the drive roller and which conveys the sheet in a conveying direction while sandwiching the sheet; a second pair of rollers which is provided on a downstream position in the conveying direction in relation to the first pair of rollers and which conveys the sheet while sandwiching the sheet; and an arm member which supports the drive roller and which is constructed 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, whereas the force for pressing the drive roller against the pinch roller decreases in the case of being driven by the sheet that is moving, wherein the first pair of rollers and the second pair of rollers are driven such that a leading end of the sheet sandwiched by the first pair of rollers is pressed against the second pair of rollers which is rotating in a direction opposite from that of the first pair of rollers or at rest thereby to correct a skew of the sheet and such that a conveying speed of the second pair of rollers is 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 the sheet having the skew corrected is conveyed by the second pair of rollers.
