Abstract: In ejecting ink from unused ink ejection ports or ink ejection ports not used frequently onto a can body to suppress ink clogging, the ink clogging is suppressed while degradation in the quality of an image to be formed on the can body is suppressed. On the surface of a can main body 110, a main image MG, which is a main image, and a strip-shaped image OG, which is a sub-image, are formed. The strip-shaped image OG is formed using ink ejection ports not used at forming the main image MG or low-frequency ink ejection ports not ejecting ink frequently. Thus, ink clogging hardly occurs in an ink jet head.
