Image forming apparatus configured to adjusting landing positions of liquid droplets
摘要
<p>A disclosed liquid-jet device includes a liquid-jet head (24) configured to jet liquid droplets; a pattern formation control unit (501) configured to control the liquid-jet head (24) and thereby to form a test pattern (400) composed of separate liquid droplets on a water-repellent part; a detecting unit including a light-emitting element (402) configured to illuminate the test pattern on the water-repellent part and a light-receiving element (403) configured to receive specularly reflected light from the illuminated test pattern (400) and to output a detection signal proportional to the received specularly reflected light; and a landing position adjusting unit configured to adjust landing positions of the liquid droplets based on the detection signal from the light-receiving element (403).</p>
