Abstract

PURPOSE:To prevent occurrence of noises in high speed recording by a method wherein a discharge electrode of electric charges is provided and when no picture signal is given to a gate electrode the impedance thereof is set to zero to accelerate the discharge characteristics. CONSTITUTION:In a magnetic fluid recording device wherein electric field is made between a needle electrode 2 and a gate electrode 1 and ink 4 on the point of the needle electrode is flied to make recordings on the paper 6, a discharge electrode 19 is provided adjacent to the gate electrode on the same surface as the gate electrode is. When voltage pulses are impressed on the gate electrode by the control of a picture signal control circuit 8, a switching circuit 20 is off and extremely high in impedance and otherwise, the switching circuit is on and extremely low in impedance to let charges on the surface of the recording paper 6 to be discharged quickly. Accordingly, the voltage can be prevented from descending by accumulated electric charges.
