High voltage generating circuit including high voltage circuit section having voltage dividing resistor and speed-up capacitor
 A high-voltage generating circuit includes a high-voltage production circuit, a high-voltage detecting circuit and a control circuit. The high-voltage production circuit includes clamping diodes to provide a good response for stabilizing a high voltage. The control circuit applies pulse-width control to a power source voltage. The high-voltage detecting circuit has a high-voltage circuit section to which a voltage of 1 kV to several tens of kilovolts is applied and a low-voltage circuit section to which a voltage of several tens of volts is applied. The high-voltage circuit section comprises a parallel circuit including voltage-dividing resistors and a speed-up capacitor. The speed-up capacitor is set to 1000 pF or less.
