ABSTRACT:
Electrostatic latent images are developed by closely positioning a developer carrying member having on a surface a developer composed of fine particles containing an organic semiconductor and being insulating at a normal state adjacent to an electrostatic latent image bearing surface in such a manner that the surface provided with the developer of the developer carrying member facaes the electrostatic latent image bearing surface, and thereby electric charges which are opposite in polarity to the electric charges of the electrostatic latent images being injected into the developer from the developer carrying member by an electric field formed between the electrostatic latent image bearing surface and the developer carrying member and the electrostatic latent images being developed by the developer.
