Abstract
A cylindrical member including a cylindrical substrate and at least one coating layer thereon is formed through an applying step of applying a coating liquid on the cylindrical substrate and a drying step of drying the coating liquid that has been applied in the applying step by induction heating device to form the coating layer. The induction heating device is disposed in the interior of the cylindrical substrate. The induction heating device has an excitation coil for generating a magnetic flux in a direction perpendicular to the axial direction of the cylindrical member. The excitation coil is disposed along the inner surface of the cylindrical substrate.
