Abstract

PURPOSE: To make production of scattering toner extremely slight by providing a flexible sealing member at the end approaching to the photosensitive drum of a developer case and allowing one end contact the magnetic brush.
CONSTITUTION: A flexible sealing member 14 of which the other end contacts the developer of a sleeve 5 with light pressure is mounted to the end 13a approaching to the photosensitive drum 1 of a developer case 13. A thin film of high electric insulation characteristic and 20μW70μ such as "Mylar " film is used for the member 14. Its free end is positioned near the developing section D and just near the toner ears. As a result, the scattering toner produced at the portion of a doctor plate 9 cannot go out from the inside of the space enclosed by the doctor plate 9, developer case 13 and sealing member 14 and is carried out by the magnetic carrier that forms the magnetic brush on the sleeve 5; therefore, the production of the scattering toner is prevented.
