ABSTRACT:
An ink jet printer using thermally fusible ink. This printer comprises an ink nozzle defining a feed passage for feeding the thermally fusible ink and an orifice for ejecting the ink, a heater for heating and fusing the ink, an ink feed roller for forcibly feeding fused ink to the orifice, electrodes for ejecting the fused ink from the orifice, and drivers for operating the electrodes in accordance with an image signal. For optimal control of fused ink flows, the feed roller defines grooves on a surface thereof, or defines ink-affined and ink-repellent surface parts arranged appropriately.
