ABSTRACT:
In droplet ejecting nozzles, a material having a small contact angle with ink is covered over the inner surface of the droplet ejecting nozzles of the nozzle plate. The nozzle plate is made of a material having a contact angle with ink that is larger than the contact angle of the material covering the inner surface of the nozzles. This provides the droplet ejecting nozzles with a stable ink droplet ejecting property.
