In a dry air blowing plate, rows of dry air outlets are arranged at given intervals in a transport direction of a photosensitive material. The interval between the dry air outlets within the row is narrower in a front zone of the dry air blowing plate that is close to a dry air inlet, whereas the interval is wider in a rear zone of the dry air blowing plate that is away from the dry air inlet. In the front zone, the velocity of dry air is lower but the aperture rate per unit area is larger. On the other hand, in the rear zone, the velocity of dry air is higher but the aperture rate is smaller. As a result, the volume of blown dry air is almost the same throughout an external surface of the dry air blowing plate, so the dry air is evenly blown to a surface of a photosensitive material.
