ABSTRACT:
A method of developing latent electrostatic images and a developer-bearing member for use in the method are disclosed, which method includes the steps of (a) forming numerous micro closed electric fields near the surface of a rotatable developer-bearing member which comprises an electroconductive support and a surface layer formed thereon comprising an electroconductive organic polymeric matrix and numerous minute charge-retainable insulating segments distributed at least one the surface of the surface layer, by electrically charging the surface of the charge-retainable insulating segments; (b) supplying a one-component type developer comprising toner particles to the rotatable developer-bearing member to hold the developer on the rotatable developer-bearing member to hold the developer on the rotatable developer-bearing member by the numerous micro closed electric fields; and (c) bringing the rotatable developer-bearing member near or into contact with a latent-electrostatic-image-bearing member which bears a latent electrostatic image to develop the latent electrostatic image with the one-component developer to a visible toner image.
