High-voltage power supply for image forming apparatus

摘要

A high-voltage power supply for an image forming apparatus compares a detected output voltage generated by dividing a high-voltage output by a voltage dividing circuit with a control value to feedback control the high-voltage output and outputs a voltage that is to be applied to a member involved in image formation. The high-voltage power supply includes a printed circuit board on which a resistor connected to a high-voltage output side of the voltage dividing circuit is mounted. A slit including a first portion and a second portion is formed in the printed circuit board. The first portion extends across a straight line connecting terminals of the resistor. The second portion continues from the first portion and extends in a direction receding from one of the terminals of the resistor.

1. A high-voltage power supply for an image forming apparatus configured to compare a detected output voltage generated by dividing a high-voltage output by a voltage dividing circuit with a control value to feedback control the high-voltage output and output a voltage to be applied to a member involved in image formation, the high-voltage power supply comprising:
a printed circuit board on which a resistor connected to a high-voltage output side of the voltage dividing circuit is mounted; and a slit formed in the printed circuit board and including a first portion and a second portion, the first portion extending across a straight line connecting terminals of the resistor, and the second portion continuing from the first portion and extending in a direction receding from one of the terminals of the resistor.
