Abstract
An inkjet printing apparatus includes a tank in which ink is contained; a print head for ejecting ink supplied from the tank to perform print operation; a supply flow path for supplying ink from the tank to the print head; a collection flow path for collecting ink from the print head to the tank; and a pump provided in the supply flow path or the collection flow path. The pump is driven, during print operation, at a first speed to circulate ink within a circulation path including the tank, the supply flow path, the print head, and the collection flow path, and the pump is driven, from a start of the ink circulation until a lapse of predetermined time period, at a second speed which is faster than the first speed.
