置に設けたことを特徴とする現像装置。 The casing has an opening facing the image carrier and both side surfaces, and the image carrier is transported by a magnetic roll having a fixed magnetized part and a cylindrical developing sleeve rotating around the outer circumference of the magnetic roll. In a developing device that performs development on an image carrier with a developer, openings corresponding to the outer periphery of the non-magnetized area at both ends of the developing sleeve have the above-mentioned openings extending over a part of the magnetized area of the sleeve. A developing device characterized in that a sealing member made of a thin plate that is attached to a side surface of a casing is provided at least at a position below the opening.
