Liquid droplet-ejecting apparatus, ink-jet printer, and liquid droplet-moving apparatus |
摘要 |
A liquid droplet-ejecting apparatus includes a liquid flow passage and a liquid discharge surface which is formed with a plurality of nozzles communicated with the liquid flow passage, a liquid-repellent area, and two hydrophilic areas for interposing the liquid-repellent area therebetween respectively and which has one of the hydrophilic areas positioned nearer to the nozzles than the other of the hydrophilic areas. A boundary of the liquid-repellent area with respect to one of the hydrophilic areas has liquid repellence lower than that of a boundary of the liquid-repellent area with respect to the other of the hydrophilic areas. The liquid droplet can be moved in a direction to make separation from the nozzles in accordance with the movement of the liquid droplet-ejecting apparatus. Therefore, it is possible to decrease the number of times of the wiping operation on the liquid discharge surface.
