BIAS POWER UNIT FOR LIQUID DEVELOPING ELECTROPHOTOGRAPHIC DEVICE

PROBLEM TO BE SOLVED: To simply generate high-voltage bias for a photoreceptor drum, a developing roller, a bias blade, etc., of a liquid developing electrophotographic device with a small number of high-voltage DC/DC converter and high-voltage series regulators. SOLUTION: Bias voltages which are independently adjusted are supplied from each of stages of bias power sources, connected in series, as loads to specified parts of the liquid developing electrophotographic device. One high- voltage DC/DC converter and a plurality of voltage regulators are provided which are connected to the output of the DC/DC converter and operate based on the ground to discharge and suck currents. The plurality of voltage regulators are arranged having their outputs connected in series and the independently adjusted bias voltages are taken out between the ground and one voltage regulator and between respective voltage regulators.
