Abstract

PURPOSE:To save power, by forming a DC voltage to be superimposed on an AC power supply of a corona charger through the use of a current flowing to the case of a separate corona charger. CONSTITUTION:The case of a charger 3 is insulated from a copying machine housing and grounded to the copying machine housing via a constant voltage element 31. A current ICD used for the charging out of corona currents generated at the charger by a DC high voltage power supply 30 is a part of a total current Icr, and others flow to the charger case. A DC voltage is generated at the terminal of a constant voltage element 31 by this current. A DC constant voltage generated by this constant voltage element is connected in series to an AC power supply 33 of a separation charger 18 to give a DC bias suitable for the AC corona discharge of the separation charger 18. Thus, the power can be saved by using the case current conventionally thrown away.
