    Abstract: A developing apparatus, includes: a developer bearing member configured to bear a developer; and a regulating member that is disposed in contact with a surface of the developer bearing member, and configured to regulate the developer borne on the developer bearing member. On the surface of the developer bearing member, a conductive portion having a first surface roughness and first electric resistance, and a dielectric portion having a second surface roughness, which is smaller than the first surface roughness, and second electric resistance, which is larger than the first electric resistance, are disposed. In a case where the developer borne on the developer bearing member is charged by friction with the regulating member, a charging polarity of the dielectric portion is the same polarity as a charging polarity of the developer.

  • Publication number: 20060142471
    Abstract: The object of the present invention is to provide a heat resistant thermally conductive material, to which fine powder such as dust, toner, and the like are hard to adhere, and which has good heat radiative properties. To attain this object, the present invention provides a heat resistant thermally conductive material, being made from an organic-inorganic hybrid material, which is prepared by heating a sol containing a metal or semimetal alkoxide, and an organo-silicon compound, plus a high thermally conductive filler, to gel said sol. Said organic-inorganic hybrid has excellent mold release characteristics, so that dust, toner, and the like don't easily adhere to the thermally conductive material, and if dust, toner and the like adhere to the thermally conductive material, they are easily removed therefrom. Further, said more highly thermally conductive filler imparts good heat radiative properties to said organic-inorganic hybrid.

  • Patent number: 7049486
    Abstract: The present invention is to provide a method which comprises providing a plant with characters of a repressor and operator both constituting a gene expression inducing system with an actinomycete autogenous regulatory factor as an inducer by gene transfer and administering the actinomycete autogenous regulatory factor to the transformed plant to thereby induce the expression of a gene placed under the control of the operator at a site of administration of the actinomycete autogenous regulatory factor. This method makes it possible to cause expression of a desired gene at a desired time and site, thus enabling even the production, in a plant, of a metabolite otherwise disadvantageous to the growth of the plant. It is also useful in preventing transformant plants from spreading through the environment by controlling the fertility thereof.
