PURPOSE: A wiper blade for a processor cartridge is provided to use four edge sides, thereby remarkably extending a lifetime of the blade. CONSTITUTION: First and second protrusions(131,132) are formed on a left side plate(130). Third and fourth protrusions(141,142) are formed on a right side plate(140). The height of the left side plate and the height of the right side plate are identical and are formed width which is same as the width of a bracket(110). A blade(120) is injected in order that a lower right side of the left side plate corresponds to an upper left side of the right side plate. Edges(133,134,143,144) of the blade are successively used. Each protrusion of the blade is combined with each groove of the bracket(111-113). |
