ABSTRACT:
A liquid droplet jetting apparatus includes: a head having a jetting port surface in which a jetting port is formed; and a maintenance unit having a cap in which a discharge port is formed, an absorber arranged in the cap, and a suction mechanism which communicates with the discharge port. The absorber includes a first absorbing portion covering the discharge port, and a second absorbing portion arranged to be in contact with the first absorbing portion. A channel resistance of the first absorbing portion with respect to a liquid is higher than that of the second absorbing portion. Accordingly, when an idle suction is performed, it is possible to discharge uniformly a liquid absorbed in the first and absorbing portions.
