COLOR ELECTROPHOTOGRAPHIC METHOD

摘要

PURPOSE:To prevent ground staining by passing successively a photosensitive sheet right after development through a conductive doctor part which is disposed in proximity to the sheet surface and to which the voltage having the potential higher than the residual potential in a non-image part and having the polarity different from the polarity of toner particles then an air blowing part. CONSTITUTION:The photosensitive sheet 3 on which a visualized image is formed is transferred to a roller 12a for a conductive doctor made of a metal, by which the voltage of the polarity higher than the residual potential in the non-image part and of the polarity different from the polarity of the toner particles is impressed to the developing soln. sticking in large amt. to the surface of the photosensitive layer and part of the excess developing soln. is removed while the residual toner particles in the excess developing soln. are removed and the film is trimmed. The sheet 3 is thereafter fed to an air blowing nozzle 13 and the carrier liquid remaining on the sheet surface is removed to the prescribed amt. without disturbing the toner layer in the image part. The greater part of the excess developing soln. is removed substantially from the surface of the sheet 3 by the above-mentioned treatment and the carrier liquid is held at 0.5-8g (about 0.5-10mum in terms of the liquid film thickness) on the basis of a unit area (m<2>). The ground staining owing to the too little remaining amt. of the carrier liquid and the deterioration in the image quality owing to the too much remaining amt. of the carrier liquid are thus prevented.
