PROBLEM TO BE SOLVED: To more easily prevent interfering electric waves from being disadvantageously discharged from an image formation device.SOLUTION: A return line of a current from a target device as a high voltage application target is formed of a harness 180 with a predetermined length. Specifically, the harness 180 has a length which does not cause the harness to resonate at a switching frequency of a high-voltage power source and also has a minimum length. This makes it possible to prevent disadvantageous generations of interfering electric waves caused by resonance of an equivalent antenna (loop antenna) at the switching frequency of the high-voltage power source, the antenna being formed of a path of currents flowing from the high voltage power source to the target device. Further, since what is required is only provision of the harness 180 forming the current return line between the high voltage power source and the target device, the realization is easier.SELECTED DRAWING: Figure 3 |
