1. A printing apparatus including a first nozzle array having ejection ports configured to eject a color material ink and arranged in a sub scanning direction and a second nozzle array having ejection ports configured to eject a reactive liquid and arranged in the sub scanning direction, the printing apparatus printing an image in a predetermined region on a print medium by scanning the first nozzle array and the second nozzle array N times (where N is an integer of 2 or greater) in a main scanning direction intersecting with the sub scanning direction, the printing apparatus comprising
a control unit configured to perform control so that out of the N scans for printing the image in the predetermined region on the print medium, a total application amount of the reactive liquid printed by first N/2 scans and a total application amount of the reactive liquid printed by second N/2 scans are different between a case where an application amount of the reactive liquid per unit area which corresponds to the predetermined region is a first amount and a case where the application amount of the reactive liquid per unit area is a second amount larger than the first amount.
