There is provided a conveying device including a controller that makes a conveying speed of a printing medium conveyed by a first conveyor unit be higher than a conveying speed of a printing medium conveyed by a second conveyor unit and makes the printing medium be conveyed while forming sagging on the printing medium between the first and second conveyor units. The controller makes a sheet sensor acquire the amount of light, which passes through the printing medium conveyed between a light emitting part and a light receiving part, as the amount of received light and determines whether or not the double-feed of the printing media has occurred only when this amount of received light is smaller than the double-feed criterion amount of received light at substantially the same conveying distance of the printing medium conveyed by the first conveyor unit.
