PURPOSE:To eliminate the disorder of the visualized part of a photosensitive layer, waste of a developer, etc., due to a defect in squeezing by blowing air to both-end gap parts formed of end parts of a photosensitive body and a squeeze roll couple at the side of a liquid developing device at the side where a body to be developed exits from a squeeze roll couple. CONSTITUTION:A lithographic plate 1 formed by providing a photoconductive sensitive layer on a base body like an aluminum plate is guide and conveyed into developing devices 6 and 7 and visualized, and when it is passed between a couple of squeeze rolls 2 and 3, gap parts 11 are formed at both ends of the lithographic plate 1. Compressed air from a blower 13 is blown from the tip of a nozzle 12 to the gap 11 to prevent a developer 9 from leaking, so that the lithographic plate 1 after development is discharged while the developer is squeezed completely. Therefore, the disorder of the toner visualized part due to a defect in developer squeezing is eliminated and there is no evil influence exerted upon a following process. |
