摘要：
In the present invention, the minimum necessary consumption of ink can recover the channel miss state of the plurality of nozzles. The present invention provides a recovery processing method of an ink jet printing apparatus for forming images using a print head having a plurality of nozzles for ejecting ink droplets. The method comprises a first step for detecting channel miss state of said plurality of nozzles, and a second step for executing at least one of different recovery processes depending on the channel miss states of said plurality of nozzles detected in the first step.
