置。[Scope of Claim for Utility Model Registration] A developer carrying member that carries and conveys a two-component developer having toner and a magnetic carrier as a magnetic brush, and a developer carrying member that carries and conveys only the toner, and a toner that carries and conveys only the toner. A toner carrying member is arranged to maintain a mutual positional relationship between the latent image carrying member and the developer carrying member so as not to come into contact with the latent image carrying member, and of the developer on the developer carrying member, only the toner is disposed. means for applying a potential difference between the developer carrying member and the toner carrying member so that the toner is electrostatically transferred to the toner carrying member, and when developing the electrostatic latent image on the latent image carrying member, the toner In a developing device that makes the latent image visible by electrostatically flying the toner on the carrier member to the latent image carrier, a toner charge eliminating member is provided to eliminate charge from the toner on the toner carrier member after development. Characteristic developing device.
