| 摘要 |
The present invention provides a method for producing a cleaning blade for use in an image-forming apparatus. The method includes the steps of roughly kneading a rubber component containing rubber derived from acrylonitrile butadiene copolymer therein by supplying the rubber derived from acrylonitrile butadiene copolymer to a rubber-kneading apparatus; kneading the rubber component, a filler essentially containing carbon black and zinc oxide therein, and a crosslinking agent containing sulfur therein by simultaneously supplying the filler and the crosslinking agent to the rubber-kneading apparatus; and press-vulcanizing a mixture consisting of a thermosetting elastomer composition obtained at the roughly kneading step to generate zinc sulfide and mold the thermosetting elastomer composition.
