PROBLEM TO BE SOLVED: To solve such a problem that a dot size formed by ejection ink increases and the practicality of a recording medium is injured because, when inkjet heads vertically disposed on a printing head are arranged such that a part of the inkjet heads are overlapped with each other and ink ejection is performed distinctly, the ejections from nozzles of overlapped inkjet heads are also overlapped. SOLUTION: A control means performs flashing ejection processing having a different amount of ink ejection respectively while recognizing the nozzles of which the ink ejection areas are overlapped and the nozzles of which the ink ejection areas are not overlapped and, thereby, even when performing the flashing ejection processing in the nozzles of which the ink ejection areas are overlapped, the dot size formed by ejection ink does not increase, the practicality of the printed matter is not injured and proper flashing ejection processing is provided.
