摘要： An ink jet printer prints an image by ejecting ink on recording medium. Information of an ink volume of the ink for application to the recording medium, for example, dot number, is specified. A first dryer dries the recording medium before forming the image. A memory stores a data table of a relationship between the ink volume and a drive condition of the dryer. A drive condition determiner determines a drive condition of the dryer from the ink volume according to the data table read from the memory. A CPU controls the dryer in the drive condition determined by the drive condition determiner. Preferably, the drive condition determiner, if the ink volume is lower than a first tolerable amount causing occurrence of cockle on the recording medium, disables the dryer.
