PROBLEM TO BE SOLVED: To suppress heating of an inkjet head and to reduce variation in ejection speed due to a temperature difference between ink channels in a multi- drop method. SOLUTION: An inkjet device comprises the ink channels and a continuous pulse applying means. The continuous pulse applying means applies an expansion/compression pulse for expanding and compressing the ink channels in ejection which is at least firstly executed in series of ejections repeated by a number of time of continuous ejections by means of the ink channels when the number of times of continuous ejections in the ink channels is not less than two and applies a non-expansion/compression pulse only for compressing the ink channels in at least one ejection from the second ejection to the last ejection. |
