ABSTRACT:
This invention relates to an electrostatic developing method for a copier, a printer or the like, and more particularly to a developing method using a one-component developer. This invention can prevent inverse electrification of the developer, which is one of the main causes of producing foggy and a fringed images, by forming the developer into a very thin layer with a doctor blade and the like, can obtain a sharp and fine image by pressing a developer holder to a latent image holder and impressing an AC bias between them, can prevent the fringe image by eliminating the unnecessary developer which adheres to the latent image holder, and can realize a high-speed development without complicated apparatus.
