にすることを特徴とする磁気ブラシ現像装置。(1) A developing container that stores developer, a rotatable developing roll that is equipped with a magnetic force generation source and forms a magnetic brush with developer on its surface, and is developed by scraping off the developer after development from the surface of the developing roll. A scraper that collects the developer into a container, an agitation conveyance member that agitates the developer scraped off by the scraper and conveys it toward the development roll again, and a developer conveyance path between the agitation conveyance member and the development roll. It consists of a conveyance restricting member that partially suppresses the flow of developer toward both ends of the developing roll, and maintains an appropriate amount of developer adhering to both ends of the developing roll where the magnetic attraction force is weak. A magnetic brush developing device characterized by a magnetic brush developing device.
的に構成されていることを特徴とする実用新案登録請求
の範囲第１項記載の磁気ブラシ現像装置。(2) The magnetic brush developing device according to claim 1, wherein the conveyance restricting member and the scraper are constructed as one unit.
