Abstract
An image forming apparatus for performing a printing job using an intermediate transfer belt is provided. The image forming apparatus has a voltage determination part for determining a predetermined level of a refresh charge corresponding to a potential difference which is generated on opposite surfaces of the intermediate transfer belt, and a power supply for supplying the refresh charge to the intermediate transfer belt so that the potential difference is offset. The power supply supplies the refresh charge to the intermediate transfer belt through a certain roller which is in contact with the intermediate transfer belt. Accordingly, the potential difference caused by the polarization in the intermediate transfer belt is offset by the refresh charge, and the variation of the resistance caused by the potential difference is prevented.
