Abstract
A drive transmission device is provided with a drive pulley driven by a motor, a driven pulley in which a bulging part crowned in a shape bulging outward in the radial direction is formed over the entire circumference of the outer peripheral surface, a belt wound around the drive pulley and the driven pulley, and a first measurement unit for measuring rotation unevenness of the drive pulley. The drive pulley has a uniform diameter in the axial direction which is a smaller diameter than that of the driven pulley. The belt is bent and deformed along the bulging part of the driven pulley so that the axial center portion is expanded outward the axial end portion. The axial end of the belt contacts the outer peripheral surface of the drive pulley, but does not contact the outer peripheral surface of the driven pulley.
