Abstract: To provide a conductive member for an electrophotographic machine that is capable of preventing hardening degradation of a surface layer that is caused by an ionic conductive agent contained in a conductive rubber elastic body layer, allowing the surface layer to be improved in durability. A conductive member 10 for an electrophotographic machine includes a conductive rubber elastic body layer 14 containing crosslinked rubber and an ionic conductive agent, and a surface layer 16 provided on an outer periphery of the conductive rubber elastic body layer 14, wherein the surface layer 16 contains a polymer and polyphenol. Examples of the polyphenol include a tannin, gallic acid, ellagic acid, pyrogallol, catechin, and chlorogenic acid.

Abstract: An endless belt for use as an intermediate transfer belt or a transfer-sheet transfer belt in an electrophotographic apparatus using electrophotographic technologies such as a full-color LBP (Laser Beam Printer) or a full-color PPC (Plane Paper Copier). At least a base layer of the belt comprises a modified polyamide imide resin formed by copolymerizing: (A) an aromatic isocyanate compound; (B) an aromatic polycarboxylic acid anhydride; and (C) a polymer having carboxylic acids at both terminals thereof.

Abstract: A grommet is mounted into an opening formed in a mating member after a wire harness containing a plurality of wires tied up in a bundle is inserted through the grommet. The grommet has a base portion formed of rubber or resin and has in the annular outer peripheral wall thereof a mounting groove fittable with an opening edge of the mating member, a roof portion extending inwardly from the opening end of the base portion, a medium diameter portion formed in a cylindrical shape having an inside diameter larger than the diameter of the wire harness to be inserted therethrough and extending upwardly in the axial direction of the grommet from the roof portion, and a small diameter portion reducing continuously in diameter from the opening end of the medium diameter portion and extending further upwardly in the axial direction of the grommet in a cylindrical manner.

Abstract: A grommet which is used to protect a wire harness in a through portion formed in a vehicle body and the like. The grommet includes a base portion formed of rubber and having a mounting groove fittable with an opening edge of a mating member, a roof portion extending inwardly from the opening end of the base portion, and a guide portion extending in a cylindrical shape in the axial direction of the grommet from the inner end of the roof portion. In the grommet, a ring-shaped cavity is formed in the inner wall portion of the grommet extending from the base portion to the roof portion, and an annular cavity is formed in the inner peripheral wall of the base portion corresponding to the position of the mounting groove.
