PROBLEM TO BE SOLVED: To provide a belt conveying device that is not affected by the shape of a belt edge during belt skew sensing, and enables highly accurate detection not causing a time delay. SOLUTION: The belt conveying device includes an endless belt stretched by a plurality of rollers; a drive means that is connected to one of the plurality of rollers and drives the roller; a plurality of belt velocity detectors that are arranged at a plurality of locations along a belt width direction perpendicular to a moving direction of the endless belt and detect the conveyance velocity of the endless belt; and a belt-inclination calculating means that calculates an inclination of the endless belt in the moving direction of the endless belt from a difference between the conveyance velocities of the endless belt detected by the plurality of belt velocity detectors.
