Abstract: An image forming apparatus is provided that forms an image with liquid developer, and a method thereof. The image forming apparatus includes a plurality of photoconductors on which developer images having carrier rates different from each other are formed with corresponding liquid developers. An image transfer member is disposed to form transfer nips with the respective photoconductors in such a manner that the developer images of the respective photoconductors are overlappingly transferred onto the image transfer member according to a transfer order predetermined on the basis of the carrier rates thereof. The developer images from the respective photoconductors are moved to an image receiving medium. Since the developer images formed on the plurality of photoconductors are overlappingly transferred onto the image transfer member according to the predetermined transfer order, the developer images previously transferred at the prior transfer nips are substantially prevented from generating a squeezed carrier beyond a predetermined limit at the posterior transfer nips. The squeezed carrier is substantially prevented from accumulating beyond the predetermined limit at the inlet side of the posterior transfer nips when the developer images are transferred from the respective photoconductors to the image transfer member.

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 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.
