Title: Developing blade
Inventor: NAOI MASATOSHI
IPC: G03G15/08
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To enable a silicone-based rubber whose environmental characteristics is excellent to be used and to enable developer to be surely electrified as required, by integrating a blade made of the silicone-based rubber whose electrifying amount is set within a specified range and a metal-made holder having spring elasticity. SOLUTION: The blade 1 made of the silicone-based rubber and the metal- made holder 2 having a spring elasticity are formed by being integrated. The electrifying amount of the blade 1 is required to be 0.5 μc/g to 30 μc/g. When the absolute value of the electrifying amount of the blade 1 is under 0.5 μc/g, toner cannot be sufficiently electrified. Besides, when it is over 30 μc/g, a defect such as fogging or the leakage of the toner is caused because more than the required quantity of toner is attached. Since the rubber-material blade 1 is required to be made to press-contact with a developer carrier with proper press- contact force a material having the spring elasticity is preferably used for the metal-made holder 2 coupled to the blade 1.
