METHOD FOR MANUFACTURING CLEANING BLADE, CLEANING BLADE MANUFACTURED BY SAME MANUFACTURING METHOD, AND ELECTROPHOTOGRAPHIC DEVICE HAVING SAME CLEANING BLADE BUILT IN

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a cleaning blade which disallows toner to pass through and an electrophotographic device constituted by building in the cleaning blade manufactured by the method. SOLUTION: Included are (1) a process of impregnating at least a portion of a blade surface made of urethane resin with an isocyanate compound, (2) a process of removing isocyanate compound left on the blade surface by blowing a hot blast whose temperature is higher than the fusion point of the isocyanate compound to the blade surface after impregnation, and (3) a process of forming a set layer by making the urethane resin forming the blade and the isocyanate compound with which the blade is impregnated react on each other.
