請求の範囲第１項に記載の装置。[Claims for Utility Model Registration] (1) A magnetic roller that attracts magnetic powder to its surface to form a magnetic brush and can be conveyed as it rotates, and a magnetic roller that is disposed close to and opposed to the roller. In a developing or cleaning device in which toner is attached or collected by brushing the image carrier with the magnetic brush, the distance from the magnetic roller to the inner surface of the housing that covers the lower side of the magnetic roller is determined by the magnetic force of the magnetic roller. A device characterized by being limited to within a range of (2) The housing that covers the lower side of the magnetic roller is provided so as to extend toward the latent image carrier from a plane tangential to the latent image carrier at the closest position between the magnetic roller and the latent image carrier. The device according to claim 1 of the utility model registration claim.
