摘要： To provide an inkjet head which includes high-density nozzle rows and which does not easily cause an ejection failure due to adhesion of ink mist around ejection orifices when a high-density image of a secondary color is printed with a small number of paths. An inkjet head includes at least two or more types of nozzle rows that eject different amounts of ink. When A is the cross section, with respect to an ink supplying direction, of an ink supply path from each ejection orifice to a supply port and L is the length of the ink supply path, the value of A/L differs between the two or more types of nozzle rows. The nozzle row of which the value of A/L is small is disposed outside an area between the nozzle rows that eject a largest amount of ink and that are arranged next to each other.
