Abstract:
The circuit board includes a contact for supplying power, in which the contact includes plural copper foil patterns each having a predetermined width, the plural copper foil patterns being formed radially from a center of the contact and connected to each other at the center of the contact. Accordingly, it is possible to enhance contact reliability of the contact while suppressing cost for connecting a high-voltage board to an image forming unit.
