ABSTRACT:
A developing device employing a liquid developer in which the development speed is increased and a developer squeezing operation may be eliminated while high-speed development and uniform development of the half-tone density may be realized simultaneously. The developing device includes a developer tank 53 containing a liquid developer 1 and a supply roll 3 for uniformly depositing the liquid developer 1 on the surface of the developer roll 54 from the developer tank 53. The liquid developer is comprised of charged toner particles 5A dispersed in an electrically insulating liquid. The charged toner particles 5A are made up of at least a coloring agent and a resin. The developing device also includes an electrical field impressing unit for impressing an electrical field across the liquid developer 1 deposited on the surface of the developer roll 2 for forming a liquid toner layer 6 formed by the charged toner particles 5A collected together. The developer roll 2, holding the liquid toner layer 6 formed by the charged toner particles 5A collected together, is pressed against a photosensitive belt member 7, on which has been formed an electrostatic latent image, for developing the latent image.
