ブラシ現像装置。[Claim for Utility Model Registration] A cylindrical sleeve is rotated around a fixed magnet, and the layer thickness of the developer adhering to the sleeve is regulated to a predetermined thickness by a regulating member. In a magnetic brush developing device configured to form a thin layer of developer and develop an electrostatic latent image on an electrostatic latent image carrier with the thin layer of developer, the gap between the sleeve and the regulating member is defined as an image area. A magnetic brush developing device characterized in that a regulating member corresponding to the outside is configured to be narrower at both ends than at the center.
