DEVELOPER AMOUNT RESTRICTING BLADE, DEVELOPING DEVICE, AND METHOD FOR MANUFACTURING DEVELOPER AMOUNT RESTRICTING BLADE

摘要

PROBLEM TO BE SOLVED: To provide a developer amount restricting blade which can electrostatically charge a developer (toner) uniformly and sufficiently by friction, has a smooth surface, realizes proper pressure to toner particles by precisely controlling contact pressure, and suppresses image defects such as a stripe and unevenness caused by the developer.;SOLUTION: A developer restricting blade in a developing device equipped with a developer carrier carrying the developer out of a developer container and the developer material restricting blade in press contact with the developer carrier is characterized in that a thin film is formed of metal different from a metal plate on the surface (charge control surface) of the metal plate at least on a side abutting on the developer carrier.;COPYRIGHT: (C)2007,JPO&INPIT
