A liquid droplet ejecting unit is disclosed wherein plural liquid droplet ejecting sub-units are provided which are arrayed in a direction substantially perpendicular to a conveying direction of a recording medium. Further, plural valves are provided which connect the respective liquid droplet ejecting sub-units and a liquid feed path. The valves comprise a valve body having an inlet port and an outlet port, and a floating member. The floating member is larger in radius than the inlet port and smaller in radius than the outlet port and has a lower specific gravity that the liquid. Thus, the floating member is floated in the liquid in the valve body and capable of closing the inlet port. An image forming apparatus using such a liquid droplet ejecting unit is also disclosed.
