Abstract: A belt driving apparatus includes a driving pulley, a driven pulley and an endless toothed belt. Each of the driving pulley and the driven pulley includes an outer circumference surface provided with a plurality of teeth. The toothed belt, wound around the driving pulley and the first driven pulley, includes an inner surface provided with a plurality of teeth arranged to mesh with the teeth of the driving pulley and the first driven pulley. The belt driving apparatus also includes an idler pulley having a belt contact surface coming into contact with the outer surface of the toothed belt. As viewed along the width direction of the belt contact surface, the idler pulley includes a center portion and two end portions sandwiching the center portion. The center portion of the idler pulley is greater in diameter than each of the two end portions.
