Abstract
A developing apparatus includes a developer carrier carrying a developer on its surface, a developer regulating member regulating layer thickness of the developer, a charge amount control member controlling the charge amount of the developer and a charge supplying apparatus downstream of the charge amount control member. The charge amount control member controls the amount of charges of the developer, by causing the developer fly over the developer carrier, using an AC voltage applied between the developer carrier and the charge amount control member, and by applying the electric charges generated by gas electrolytic dissociation caused by the AC voltage. By this structure, a developing apparatus can be provided which can improve stability of development and image quality, without necessitating delicate arrangement of the component materials of the developer.
