Abstract
A developer-bearing member with the surface thereof being composed of minute dielectric portions and minute electroconductive portions which are mixedly distributed, the dielectric portions containing an amino coupling agent, is used in an image formation method including the steps of forming numerous micro closed electric fields near the surface of the developer-bearing member by causing the developer-bearing member to selectively hold electric charges on the surface thereof, supplying a non-magnetic one-component type developer containing a toner to the surface of the developer-bearing member to hold the toner on the surface of the developer-bearing member by the micro closed electric fields, and developing a latent electrostatic image formed on a latent-electrostatic-image bearing member to a visible toner image by the toner.
