摘要:
A method for manufacturing a blade for electrophotographic devices and a blade for electrophotographic devices are provided. The method includes: an impregnation step of impregnating, from the surface of at least a part of a blade-shaped substrate containing urethane rubber, with a blocked isocyanate in which an isocyanate group is blocked with a blocking agent, wherein the part includes a portion that comes into contact with a mating member; and a curing step of dissociating the blocking agent from the blocked isocyanate impregnated into the substrate in the impregnation step, and then curing the released isocyanate in the substrate to form a cured portion in at least the part of the substrate including the portion that comes into contact with the mating member. In the method, the isocyanate released from the blocked isocyanate includes an aromatic isocyanate.
