PROBLEM TO BE SOLVED: To provide a recording instrument which can improve corrosion resistances to a photo-curing ink, prevent ink clogging and ink leakage even when used for a long time, stably secure an ink droplet discharging precision, and also reduce effects on ink sensitivity. SOLUTION: In an ink liquid feeding member for inkjet using the photo-curing ink, a liquid feeding pump for feeding the ink from an ink storing part to an inkjet head is a tube pump. A ratio A/B of a contact area A (cm<SP>2</SP>) between a tube and a tube pump pressuring member for crushing the tube when feeding the photo-curing ink, and a tube pipe internal area B (cm<SP>2</SP>) is not smaller than 10 but not larger than 150.
