Patent ID: 8016386

Claim:
An ink jet printing apparatus that performs scanning of a printing head in a scan direction, said apparatus comprising a printing head provided with: two sets of ejection opening arrays, each of which comprises two ejection opening arrays and which are arranged in the scan direction, the two sets of ejection opening arrays ejecting a different color of ink from each other, wherein the two ejection opening arrays of each of the two sets of ejection opening arrays are arranged adjacently to each other in the scan direction so that ink is supplied to the two ejection opening arrays of each of the two sets of ejection opening arrays through a common supply path, and a plurality of ejection opening arrays, which eject a different color of ink from the two sets of ejection opening arrays, at both sides of the two sets of ejection opening arrays, wherein ink is supplied to the plurality of ejection opening arrays through separate supply paths, wherein an arrangement order of the plurality of ejection opening arrays provided at one of the both sides of two sets of ejection opening arrays is reverse order to an arrangement order of the plurality of ejection opening arrays provided at the other of the both sides of two sets of ejection opening arrays, and wherein one of the two sets of ejection opening arrays is a set of ejection opening arrays for ejecting yellow ink and the other of the two sets of ejection opening arrays is a set of ejection opening arrays for ejecting black ink, and the plurality of ejection opening arrays provided at the both sides of the two sets of ejection opening arrays include ejection opening arrays for ejecting cyan ink and magenta ink respectively.
