Abstract: A developing method expediting the development process, eliminates squeezing and achieves both high-speed development and uniform development at a half tone density. The development method employs a liquid developer 50 comprised of charged toner particles dispersed in an electrically insulating liquid. The charged toner particles are made up at least of a coloring agent and a resin. The liquid developer 50 is uniformly deposited on the surface of the developer carrier 51 and an electrical field is impressed for generating a liquid toner layer comprised of the charged toner particles assembled together. A charge carrier 55 on which is formed an electrostatic latent image is contacted under pressure with the developer carrier 51 holding the liquid toner layer comprised of the charged toner particles assembled together in order to effect development.
