主权项 1. A liquid droplet discharge device comprising: a liquid droplet discharge head in which a liquid repellent layer is formed over a liquid droplet discharge surface of a nozzle plate, the liquid repellant layer including a liquid repellant layer portion and a liquid resistant protective layer portion, the liquid repellent layer portion being disposed on the liquid-resistant protective layer portion, the nozzle plate defining a nozzle opening; a fixing plate that fixes the liquid droplet discharge head to a head supporter; and a wiping member that wipes the liquid droplet discharge surface by a relative movement with the liquid droplet discharge head, wherein the nozzle plate includes an end surface that is adjacent to the fixing plate, the end surface including a coated portion and a non-coated portion, the coated portion being coated by the liquid repellent layer that is continuously coated from the liquid droplet discharge surface to the coated portion, the non-coated portion being not coated by the liquid repellent layer, and the fixing plate does not overlap the liquid droplet discharge surface and fixes the liquid droplet discharge head to the head supporter at an initial point side of wiping using the wiping member.
