ABSTRACT:
A liquid development and transfer apparatus includes an application roller for supplying developing solution to an electrostatic latent image carrier surface, and an applicator for providing developing solution uniformly on the surface of the application roller. A DC bias voltage is applied to the application roller to influence development of an electrostatic latent image of the carrier, and an AC bias voltage is applied between the application roller and the applicator to prevent developer from collecting thereon as might be caused by residual potentials. After development of the electrostatic latent image for a given color on the electrostatic latent image carrier, solvent contained in the developed image layer is removed or heated, and color superimposing development is performed consecutively in similar fashion for other colors. By collectively transferring the resulting developed image to a recording paper or an intermediate transfer medium, color superimposing development can be accomplished with high accuracy without mixing of the colors of the developing solutions.
