Apparatus for cleaning the transfer roller of wet-type image forming apparatus and Method thereof

摘要

The transfer roller cleaning apparatus and a cleaning method of a wet image forming apparatus is disclosed. Measuring a resistance between the disclosed transfer roller according to the present invention, the cleaning method comprising: applying a measurement voltage to the transfer roller, a transfer back up on the basis of the applied measurement voltage roller and the intermediate transfer member and transfer roller, the measured resistance step of calculating on the basis of the toner concentration of the developer on the transfer roller, and characterized in that the calculated toner concentration comprising the step of applying the step, and the cleaning voltage supplied to the carrier when not less than a certain reference value. According to this, and to maintain proper cleaning efficiency by adjusting the cleaning voltage developing in accordance with the toner concentration deposited on the transfer roller, there is an effect that when the toner concentration of less than a certain reference value is supplied to the carrier to increase the cleaning efficiency. ; Wet image forming apparatus, the transfer roller, the toner density, a carrier supply unit, the cleaning voltage
