Abstract
An inkjet image forming apparatus includes a print head, an ink tank to store ink, an ink feeding path to feed the ink from the ink tank to the print head, a filter disposed on the ink feeding path, and a press unit disposed on the ink feeding path between the filter and the print head, to press the ink present in the ink feeding path toward the ink tank. The press unit repeats a first operation to press the ink in the ink feeding path toward the ink tank, and a second operation to suck the ink in the ink feeding path.
