PROBLEM TO BE SOLVED: To provide an image forming device equipped with the high voltage power source at a low cost in a compact size, making at least, one of the high voltage among plural required high voltage power sources possible to be applied from the power source being disposed in order to output another high voltage necessary for the image forming device. SOLUTION: This image forming device is made possible to eliminate the transfer cleaning power source by applying transfer cleaning bias from a charge bias power source transformer 114 outputting the charge DC potential, and making the charge DC power source and the transfer cleaning power source common, among power sources of the conventional image forming device. Moreover, by inserting a transistor 130 capable of making the transfer cleaning potential turned off in the circuit, for the time when the charge DC potential is output, and the transfer cleaning potential is not required, when the charge DC potential is output, it is made possible to be turned on/off at the optional timing. |
