Abstract
An ink jet apparatus is described which includes a suction recovery device and control thereof so as to appropriately remove air bubbles created in an ink jet head. The ink jet apparatus is characterized in that at each unit time, the ambient temperature of the ink jet head is measured and the temperature of the ink jet head is presumed, and the number of dots discharged for a unit time is corrected on the basis of the measured ambient temperature and the temperature of the ink jet head obtained by the presumption, and the control of the recovery operation is effected in conformity with the corrected number of dots.
