Developing device and a developing method having a conductive member upstream of image data forming member |
摘要 |
A developing device for developing, by using a developer, a latent image formed on a surface of an image data forming member including a developer accommodating section for accommodating the developer; a first developer retaining member for receiving the developer from the developer accommodating section and transporting the developer; a second developer retaining member for receiving the developer from the first developer retaining member and making the developer adhere to the latent image formed on the image data forming member; a conductive member opposed to the second developer retaining member with an appropriate space interposed therebetween; a first voltage applying member for applying a voltage between the first developer retaining member and the second developer retaining member; a second voltage applying member for applying a voltage between the second developer retaining member and the surface of the image data forming member; and a third voltage applying member for applying a voltage between the second developer retaining member and the conductive member in order to form an electric field in the space therebetween.
