Droplet ejecting apparatus, a droplet adherence preventing method and a cleaning method for cleaning a recording medium carrier roller

1. A droplet ejecting apparatus comprising:

a recording medium carrier portion provided with recording medium carrier rollers conveying a recording medium;

droplet ejecting portion discharging droplets onto the recording medium; and

droplet adherence preventing liquid applying portion applying droplet adherence preventing liquid preventing adherence of the droplets to at least one of the recording medium carrier rollers, the droplet adherence preventing liquid comprising a zinc soap having a molecular weight of about 1,000 or less.

2. The droplet ejecting apparatus of claim 1 , wherein the recording medium carrier rollers are arranged at a downstream side of the droplet ejecting portion with respect to a conveyance direction of the recording medium.

3. The droplet ejecting apparatus of claim 1 , wherein the recording medium carrier rollers are arranged in a pair so as to nip the recording medium having droplets discharged from the droplet ejecting portion adhered thereto.

4. The droplet ejecting apparatus of claim 3 , wherein the droplet adherence preventing liquid applying portion applies the droplet adherence preventing liquid to one of the recording medium carrier rollers that is brought into contact with the surface of the recording medium onto which the droplets are discharged.

5. The droplet ejecting apparatus of claim 4 , wherein the droplet adherence preventing liquid applying portion comprises a droplet adherence preventing liquid applying member in which the droplet adherence preventing liquid is impregnated, the droplet adherence preventing liquid applying member being brought into contact with at least one recording medium carrier roller contacting a surface of the recording medium to which droplets are discharged so as to apply the droplet adherence preventing liquid thereto.
