Disclosed is an ink-jet printer which uses an actinic ray-curable ink-jet ink containing a cationic-polymerizable compound and is capable of performing stable image recording with inhibiting formation of precipitates within the printer and an image forming method by use thereof. The ink-jet printer ejecting an ink comprising a cationic-polymerizable compound onto a recording medium, characterized in that the ink-jet printer comprises ink-contact members which constitute an ink tank retaining the ink and an ink supply passage of from the ink tank to a recording head ejecting the ink and the ink-contact members are each comprised of a material which does substantially not undergo electron transfer with the ink.
