Abstract
A squeegee apparatus of a liquid electrophotographic printer is provided. The apparatus has a squeegee roller for pressing a photoreceptor belt to squeegee excess developer from an image developed on the transfer surface of the photoreceptor belt. A squeegee backup roller is provided opposite to the squeegee roller, to press a reverse surface of the photoreceptor belt. The squeegee apparatus includes a heating device installed in the squeegee backup roller, for heating the photoreceptor belt at a predetermined temperature. During printing, since the photoreceptor belt is squeegeed while it is heated to a predetermined temperature, the squeegeeing efficiency is enhanced, thereby improving the printing quality of the printer.
Claims3
A squeegee apparatus of a liquid electrophotographic printer having a squeegee roller for pressing a photoreceptor belt to squeegee excess developer liquid from an image developed on a transfer surface of the photoreceptor belt, and a squeegee back up roller for pressing an opposite surface of the photoreceptor belt which is reverse to the transfer surface, the squeegee back up roller disposed opposite to the squeegee roller, the squeegee apparatus comprising a heating means installed in the squeegee backup roller, for heating the photoreceptor belt at a predetermined temperature, wherein the squeegee backup roller consists of a core layer, an outer layer and an insulation layer formed therebetween, and the heating means includes a printed heat wire printed on the insulation layer, a connecting coat unit formed on the outer layer to be electrically connected to the printed heat wire, and an electricity supply unit formed in contact with the connecting coat unit, for supplying electricity to the printed heat wire.
