載の現像装置。[Claims for Utility Model Registration] (1) Development in which a developer is conveyed to an image carrier on the surface of a rotating sleeve, and an image is visualized by bringing the developer close to or in contact with an electrostatic image on the surface of the image carrier. In the apparatus, at both ends of the rotating sleeve,
A ring-shaped protrusion is formed integrally with the rotary sleeve, and the outer peripheral surface of the ring-shaped protrusion comes into contact with the surface of the image carrier, and a seal member is provided on the side surface of the apparatus main body that slides into contact with the outer circumferential surface of the ring-shaped protrusion. A developing device characterized in that the distance between the surface of the rotating sleeve and the surface of the image carrier is regulated. (2) The developing device according to claim 1, wherein the outer circumferential surface of the ring-shaped convex portion is rotated at substantially the same speed as the surface of the image carrier.
