As shown in FIG. 7(e), an electric field is generated at timing T3 at which an ink droplet 14 is divided, end moves the negative ions toward a main ink portion 14m As shown in FIG. 7(e'), a resultant main ink droplet 14M has an increased charging amount of -3 q, and a satellite ink droplet 14S has a decreased charging amount of -6 q. When the main ink droplet 14M and the satellite ink droplet 14S have the mass of lm and Qs, respectively, then the relative charging amounts of the main ink droplet 14M and the satellite ink droplet 14S are both -3, Hence, the deflection amount of the satellite ink droplet 14S is approximately equal to the deflection amount of the main ink droplet 14M Accordingly, the satellite ink droplet 14S and the rain ink droplet 14M impact the recording sheet 60 on the same spot or on the extremely close spots, thereby forming a single dot,
