Abstract
The image forming apparatus includes an upstream side chamber arranged further on an upstream side with respect to an ink flowing direction than a head in a circulating path and configured to temporarily store the ejection liquid that should be supplied to the head through the circulating path, a downstream side chamber arranged further on a downstream side than the head and further on the upstream side than the upstream side chamber in the circulating path and configured to temporarily store the ejection liquid collected from the head, and a pressure-difference adjusting mechanism configured to form a first pressure state in which the pressure in the downstream side chamber is lower than the pressure in the upstream side chamber and the head and a second pressure state in which the pressure in the upstream side chamber is lower than the pressure in the downstream side chamber.
