ABSTRACT:
An electrographic development process wherein an electrically charged developer comprising electrically conductive particles with a volume resistivity of 10.sup.9 .OMEGA.cm or less and toner particles with a volume resistivity of 10.sup.12 .OMEGA.cm or more, with the mixing ratio of the respective particles being from 1:99 to 40:60, is brought into contact, or proximity, with a latent electrostatic image with a polarity opposite to that of the electrically charged developer, and the latent electrostatic image is developed to a visible image by the developer, through the steps of supplying the developer to a developer doner member; forming a developer layer thereon with a thickness ranging from 150 .mu.m to 300 .mu.m; subjecting the developer to charge injection to a potential ranging from -150 V to -500 V; and supplying the developer to a latent electrostatic image bearing member for development of the latent electrostatic image thereon.
