Abstract
A printing apparatus includes a printing unit that performs printing on a printing medium, a transporting belt that transports the printing medium and has an endless shape, and a belt-driving roller that causes the transporting belt to circulate and has a cylindrical shape. In the transporting belt, a magnetic scale having a magnetic pole changing at a predetermined pitch is arranged along a transport direction of the printing medium. The belt-driving roller includes an outer circumferential surface constituted of a magnet body, and is in contact with the transporting belt at the outer circumferential surface. The circumferential length of the outer circumferential surface of the belt-driving roller is an integer multiple of the pitch of the magnetic scale.
