  • Silicone rubber sponge and rubber-covered roller
    Patent number: 9260606
    Abstract: Provided are a silicone rubber sponge that forms an elastic layer of a pressure roller of an image-forming apparatus, and that has a high mechanical strength so as to be used in a high-speed image-forming apparatus or a color image-forming apparatus, and a rubber-covered roller including the silicone rubber sponge. The silicone rubber sponge is produced by mixing expanded resin microballoons with a low-molecular-weight silicone rubber to prepare a compound A, mixing a high-molecular-weight silicone rubber with the compound A to prepare a silicone rubber compound, and heating the silicone rubber compound at a temperature lower than a softening point of the resin microballoons to cure the silicone rubbers.

  • Polyimide tube, method for production thereof, method for production of polyimide varnish, and fixing belt
    Patent number: 8263199
    Abstract: A polyimide tube composed of a polyimide resin composition in which 5 to 23.5 volume percent of boron nitride and 1 to 15 volume percent of an acicular substance are dispersed as a filler in a polyimide resin on the basis of the total volume of the composition, a method of producing the tube, a method of producing a polyimide varnish used for producing the tube, and a fixing belt including the tube as a base member are provided.
