Abstract
An image formation device includes an inkjet head that ejects ink onto a sheet, IR heaters that dry the ink ejected on the sheet, and warm air heaters between the IR heaters. At the IR heaters, a peak wavelength of infrared rays is set to be less than or equal to 1.2 μm. By adjusting temperature of the IR heaters and temperature and wind speed of the warm air heaters, during an initial stage of drying in which a moisture content derived from ink at the sheet is greater than or equal to 4.0 g/m2, heating is carried out under a condition that a paper surface temperature of the sheet becomes less than or equal to 100° C., and, after the moisture content derived from ink at the sheet becomes lower than 4.0 g/m2, heating is carried out such that the paper surface temperature of the sheet exceeds 100° C.
