Beschreibung
Zusammenfassung:	An inkjet printing apparatus includes a first and second tanks, and a printer section including an inkjet head which ejects ink droplets toward a printing medium. The inkjet printing apparatus includes a first supply system which supplies ink from the first tank to the second tank, a second supply system which includes an ink supply pump and supplies ink from the second tank to the printer section, and a remaining amount detection unit which detects the amount of ink remaining in the first tank. The remaining amount detection unit calculates the amount of ink transferred from the first tank to the second tank in a measurement period during which ink is supplied from the first tank to the second tank, based on an increase in the amount of the ink stored in the second tank in the measurement period and the operation state of the pump in the measurement period.
