Abstract
In the air-blow dryers 7a, 7b, the back surface M2 of the printing medium M is supported by the rollers 74 while the hot wind is injected from the nozzles 76u to the front surface M1 of the printing medium M. By extending the printing medium M along the rollers 74, the evaporation of the moisture can be promoted by the hot wind while the formation of creases of the printing medium M is suppressed against the influence of the temperature distribution caused by the latent heat of the moisture on the printing medium M. After a certain amount of the moisture is evaporated, the temperature of the printing medium M becomes relatively uniform. In the air-blow dryers 7c, 7d, the printing medium M is dried by injecting the hot wind to the printing medium M from the nozzles 76l and 76u from both sides.
