An ink guide member extending into a lower portion of the main chamber andalso being in contact with the first surface of the film forming member, wherein as ink inthe main ink chamber is consumed a differential pressure between the first and secondsurfaces of the film forming member causes a gradual expansion of a liquid meniscus filminto an air bubble on the film forming member to maintain a constant negative pressurein the main ink chamber.
