Liquid development and transfer apparatus for electrostatic latent image

A liquid development apparatus for developing an electrostatic latent image of an electrostatic latent image carrier using liquid developer, said apparatus comprising:

• an application roller for applying developing solution to the electrostatic latent image carrier where said electrostatic latent image is formed;
• an applicator including a dish-shaped plate disposed face-to-face with the application roller for receiving developing solution and providing uniform application of developing solution to the surface of the application roller;
• an injector which has a plurality of small openings for injecting developing solution within the dish-shaped plate of the applicator;
• DC power source means for providing a bias voltage to the application roller for influencing development of the electrostatic latent image;
• and
• AC power source means for providing an AC bias voltage between the application roller and the dish-shaped plate of the applicator for preventing developer from collecting on the application roller so as to assure proper clearance thereof with respect to the electrostatic latent image carrier and within the dish-shaped plate of the applicator.

A liquid development apparatus for developing an electrostatic latent image of an electrostatic latent image carrier with a rotating roller type development electrode using liquid developer, said apparatus comprising:

• an application roller for applying developing solution to the electrostatic latent image carrier where said electrostatic latent image is formed;
• developing solution supply means for providing developing solution uniformly on a surface of the application roller, said developing solution supply means having a plurality of small openings arranged in adjacent positions for injecting developing solution to a surface of the application roller;
• DC power source means for providing a DC bias voltage on the application roller;
• and
• AC power source means for applying an AC bias voltage between the application roller and the developing solution supply means.
