Abstract:
1. An image printing apparatus of an ink jet printing system, comprising: first and second rotary drums adapted to have a printing sheet wound therearound; first and second ink jet printing heads which correspond respectively to the first and second rotary drums, and each of which discharges photo-curing ink in order to print an image on the printing sheet wound around the corresponding rotary drum; a first irradiation optical path along which rays are irradiated to a first image printing surface of the printing sheet wound around the first rotary drum; a second irradiation optical path along which rays are irradiated to a second image printing surface of the printing sheet wound around the second rotary drum; and light irradiation means for irradiating the rays along the first and second irradiation optical paths to irradiate the image printing surfaces by optical scanning via a reflecting mechanism; wherein the printing sheet is wound around the first rotary drum with the first image printing surface facing outward, and is then wound around the second rotary drum with the second image printing surface facing outward.
