APPARATUS FOR PROVIDING DEVELOPING AGENT AND APPARATUS FOR PREVENTING PRESSURE INCREASEMENT OF DEVELOPING CHAMBER

摘要

PURPOSE: An apparatus for providing a developing agent and apparatus for preventing a pressure increasement of a developing chamber is provided to prevent a sharply increased pressure in the developing chamber by floating the developing agent in the developing chamber. CONSTITUTION: A developing agent apparatus is installed at a path in which a toner is provided to a developing chamber(204). The developing agent apparatus provides the toner from a toner chamber(200) to the developing chamber(204), or provides the toner remained in the developing chamber(204) to the toner chamber(200). The developing agent apparatus has a first film(206), a second film(210) and a rotating rod(208). The first film(206) is installed between the toner chamber(200) and the developing chamber(204) for blocking the toner chamber(200) and the developing chamber(204). The rotating rod(208) is installed at a lower side of the first film(206).
