Image forming apparatus for preventing resistance variation of intermediate transfer belt and method thereof |
摘要 |
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 voltage corresponding to a potential difference which is generated on opposite surfaces of the intermediate transfer belt, and a power supply for supplying the refresh voltage to the intermediate transfer belt so that the potential difference is offset. The power supply supplies the refresh voltage 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 voltage, and the variation of the resistance caused by the potential difference is prevented.
