A printhead of an ink jet printer includes plural ejection nozzles for ejecting ink. In an ink ejection inspecting method for the printhead, the ejection nozzles are photographed in the printhead, to output image data. The image data is analyzed by the pattern recognition, to output analysis result information. According to this, it is judged whether an ejecting state of the ejection nozzles is acceptable or unacceptable.
