Electrostatic recording head providing voltage regulation to voltage applied to needle electrodes

There is provided an electrostatic recording head capable of moderating variable density striations generated on a recording blank form. In an applied voltage regulating unit, a closed circuit is formed by connecting a regulator (42), a resistor (32), a diode (34) and a resistance (R1) and a transistor (T1) provided in a driving circuit (16 or 18) in series in one needle electrode (12). Here, a cathode side of the diode (34) is connected to the needle electrode (12), and another end of the regulator (42) is connected to the driving circuit (16 or 18). A regulated voltage determining means (44) determines the voltage to be applied to each needle electrode (12) in accordance with the picture image density detected by a picture image density detecting unit (46) and the humidity detected by a humidity sensor (48), and regulates a voltage value of a regulator (42) based on the determined voltage. Thus, the voltage applied to the needle electrode (12) can be regulated by applying an electric current to the circuit and dropping the voltage with resistance 32 and resistance R1.
