ABSTRACT:
A developing apparatus in which a nonmagnetic carrier is used; a developer forward member having a conductive surface and forwarding a nonmagnetic toner and the resin carrier by stirring is disposed so as to confront a toner carrying body with a gap interposed therebetween and so as to arrange a part of the surface thereof close to an inner wall surface of a frame of the apparatus, the frame having a surface profile corresponding to a surface profile of the forward member; and a voltage applying means is arranged so that the voltage applying means applies such a voltage to generate an electric field for attracting the toner in the developer toward the toner carrying body and attracting the resin carrier toward the developer forward member in the area where the toner carrying body confronts the developer forward member.
