A printing head, having ejection openings arranged symmetric, is to be suppressed from deteriorating in image quality as caused by the manufacturing errors or problems in mounting accuracy thereof. Specifically, in the case the printing head inclines, for example, by 0.5 degrees at the line connecting between the corresponding ejection openings of ejection opening arrays relative to the scanning direction, deviations occur in the dots formed through the ejection opening arrays with reference to the dot formed through other ejection opening array. However, the deviations can be minimized by arranging adjacently small-ejection opening arrays for cyan and magenta with a spacing reduced between those ejection opening arrays.
