Abrégé
Disclosed is a conductive multifilament yarn for forming a conductive brush, the yarn comprising conductive fibers obtained by coating the surface of synthetic fibers with carbon nanotubes. The synthetic fibers each may have a fineness of 30 dtex or less. The synthetic fibers each may have 3-6 recesses or grooves extending in the lengthwise direction, and have a cross section in the shape of a multi-blade leaf or in a star shape. The conductive multifilament yarn has high conductivity and may have an electrical resistance at 20ºC of 1×106-1×1011 Ω/cm. The conductivity of the yarn is highly even, and the standard deviation of the logarithm of the electrical resistance may be 1.0 or less. Since the conductive multifilament yarn has even and advanced conductivity characteristics (electrification or charge neutralization characteristics), which are required of conductive brushes for electrophotographic devices, the yarn is suitable for use as a cleaning brush for electrophotographic devices.

Weatherseals are provided by a pair of base members which may be attached to a pile formed by winding fibers around a band as the band travels along an endless path. A section of the pile on one side of the endless band is cut to provide cut pile section and a continuous pile section. The continuous pile section forms the bow, arch or loop by disposing the base members in side-by-side, back-to-back, or perpendicular relationship. The cut pile section may be removed at the base members or halves of the cut pile section maybe left in place. The cut pile section halves and the outside surface of the bow, arch, or ioop may be attached by base members to a member, such as by adhesive or via one or more T-shaped slots, that is in sealing relationship with another member and engagable therewith to provide a resilient seal.
A shutter device has a pair of support frames (12) parallelly arranged, spaced at a predetermined distance apart, and also has a shutter (14) placed between the support frames (12). The support frames (12) support the left and right sides (14A) of the shutter (14) so as to allow the shutter (14) to reciprocate in its longitudinal direction. A weather strip (20) is placed between each side face at each side (14A) of the shutter (14) and a facing surface of the support frame (12), which facing surface faces the each side face. Each weather strip (20) has a long base member attached to each side frame (12), fluff raised on the base member, and a film member (23) provided on the base member. The film member (23) has higher rigidity than the fluff and the height of the film member (23) in the direction toward the facing surface of the support frame (12) is less than that of the fluff. The construction reduces sliding resistance of the shutter (14), and when the shutter (14) receives strong external force, it suppresses play of the shutter (14).
