を特徴とする現像装置。[Claims for Utility Model Registration] A static image forming apparatus that develops a latent image formed on a photoreceptor by carrying a developer on the circumferential surface of a rotating developing roller and conveying the developer to a developing section facing a photoreceptor. In a developing device of an electro-recording device, the developing roller has a resistance heating layer formed on the surface of a metal core, and between the metal core and a member that is in pressure contact with or close to the developing roller. A developing device characterized by having a means for energizing.
