Abstract There is provided an apparatus for driving a squeegee roller for a liquid electrophotographic printer including a squeegee gear coaxially installed at one shaft end of the squeegee roller, a driving gear installed such that in a state where the squeegee roller contacts the photoreceptor belt, the centre of the rotation shaft thereof is positioned on a plane perpendicular to the elevating direction of the squeegee roller and passing through the centre of the rotation shaft of the squeegee roller, to be engaged with the squeegee roller, and a driving source (M) having an output shaft for rotating the driving gear to drive the squeegee roller to rotate in a reverse direction to the rotating direction of the photoreceptor belt. Therefore, even when a drip line removal mode of the printer is terminated to be switched to a stop mode, the squeegee roller does not stop but keeps rotating in reverse while it is in the course of being lowered from the photoreceptor belt, thereby removing a drip line on the photoreceptor belt as accurately as possible.
