PROBLEM TO BE SOLVED: To provide a sheet conveyor capable of enhancing the dimensional accuracy of parts used therein, while reducing the number of part items and assembly man-hours, and preventing uneven exposure. SOLUTION: The sheet conveyor 4 transmits the driving force of a driving motor 5 to a driving roller 41 via a belt transmission mechanism 6 having an endless drive transmission belt 67, thereby driving the driving roller 41 to rotate so as to convey sheets. A portion of the roller surface 43 of the driving roller 41 is formed into a belt abutting surface 65 across which the drive transmission belt is stretched.
