Abstract
An objective of the present invention is to provide an inkjet printing apparatus and an ink filling method capable of restraining a decrease in its availability. For that purpose, in a case where a predetermined negative pressure (determination pressure) is not reached within a predetermined time (determination time) in normal filling operation (first filling operation), it is assumed that a leakage occurs in a cap member, and second filling operation is performed.
