Abstract
In a constitution of primary-transfer-high-voltage-less in which a power source dedicated to primary-transfer, in the case where voltage applications for determining primary-transfer and secondary-transfer voltages are carried out concurrently, there is a possibility of improper primary-transfer. The possibility is decreased by controlling a power source so that a voltage drop of a Zener diode maintains a Zener breakdown voltage.
