Abstract: The effects on an image are maximally decreased with respect to ejection by printing elements included in the low flow rate areas of a serial channel in an inkjet printing apparatus that uses a joined head in which multiple chips provided with multiple printing element arrays are disposed. For this purpose, print data is distributed to individual printing elements at a joining portion between two chips, such that fewer printing elements execute ejection operations on a printing element array A distanced farther from the center line of a base plate than a printing element array D nearer the center line. Doing so suppresses ejection by printing elements included in low flow rate areas which manifest near the turns of an ink channel, and reduces density defects due to ejection by such printing elements.
