Abstract:
A fluid ejection device has a fluid ejection head that ejects fluid droplets onto printing paper; a carriage that carries the fluid ejection head; and a static elimination member or charged member affixed to either or both the fluid ejection head and carriage. The static elimination member is configured to contactlessly eliminate the electric charge of an object, and the charged member has a polarized charge.
