High-voltage power supply and image forming apparatus

A high-voltage power supply for a first load and a second load, the first load being connected between a first node and a second node, the second load being connected between the first node and a third node, the high-voltage power supply comprising:

• a first high-voltage output circuit having a first output connected to the second node, and a second output, the first high-voltage output circuit being capable of outputting a first voltage having a first polarity to the first load;
• a voltage clamping element connected between the second output and the first node, the voltage clamping element being configured to clamp a voltage at the second output to a second voltage having a second polarity opposite to the first polarity, the first high-voltage output circuit being connected between the voltage clamping element and the second node;
• a second high-voltage output circuit having a third output connected to the second output, and a fourth output, the second high-voltage output circuit being capable of outputting a third voltage having the first polarity;
• and
• an output circuit connected to the fourth output and having a fifth output connected to the third node, the output circuit being configured to produce a voltage having the first polarity and a voltage having the second polarity using the third voltage and a voltage derived from the second voltage and output the produced voltages to the second load.
