ABSTRACT:
A method of and apparatus for developing a latent electrostatic image in which a one-component type developer is deposited on the surface of a developer applicator having a conductive and elastic endless surface and the developer applicator is brought into pressure contact with a latent electrostatic image bearing member having a latent electrostatic image thereon. The peripheral speed of the developer applicator is slightly greater than that of the latent electrostatic image bearing member. In the case where the developer on the surface of the developer applicator is charged by charge injection from a blade electrode which is in contact with the developer, the present development apparatus is provided with a means for insulating the opposite top end portions of the blade electrode from the surface of said developer applicator.
