Abstract: PROBLEM TO BE SOLVED: To provide a magnetic driving system for realizing a fluid ejector insensitive to the physical properties of a fluid. SOLUTION: In the driving system for the fluid ejector 100 for discharging and replenishing the fluid, a magnetic field is generated by a coil or a magnetic material element, which is mounted inside the fluid ejector 100, and magnetic force in the magnetic field causes a change in volume capacity between a piston 110 and a face plate 120 for the purpose of discharging and replenishing the fluid.
