Claims

[Scope of utility model registration request]

a cylindrical developing sleeve having a magnet inside and made of a non-magnetic material; a magnetic developer that adheres to the developing sleeve by the magnetic force of the magnet and develops a latent image on an image carrier;
In the developing device including a regulating member for regulating the amount of the magnetic developer adhering to the developing sleeve, positioning members for the regulating member are provided at both ends of the developing sleeve, and the positioning member is positioned from the axis of the developing sleeve. It has a shape in which a plurality of cams with different distances are combined, and has a retaining part that engages with the regulating member, and when the circumferential surfaces of the note regulating member and the positioning member come into contact with each other, the regulating member and the developing sleeve are brought into contact with each other. A developing device characterized in that the distance between the developing device and the developing device is determined. −
