Abstract: An insulator includes a housing portion. The housing portion is composed a silicone rubber obtained by curing a composition containing diorganopolysiloxane (A) and a fine silicon powder (B) by heating, and a methylalkylpolysiloxane oil (C). The diorganopolysiloxane has at least two silicon atom-bonded alkenyl groups in one molecule. The methylalkyl-polysiloxane oil (C) has each of both terminal ends of each molecular chain blocked with a trialkysiloxy group and possessing a viscosity at 25.degree. C. being 1 to 1,000 centistokes, and is incorporated into the above composition in an amount of 1-100 parts by weight per 100 parts by weight of the component (A).

Abstract: A fixing roller used in an electrophotographic device includes a coupling with a drive key that engages an end of a pressing roll that contains a key groove. Disposed between the coupling and the end of the pressing roll is a spacing member. This spacing member decreases the rate at which the key groove and the drive key deteriorate when two fixing rollers are used as pair to fix toner on a printed page. The spacing member is made of plastic, a sintered metal alloy, or other material. Also, the spacing member is lubricated to further prevent friction and the key groove of the pressing roll is lined with an abrasion resistant material to further prevent deterioration of the drive key and the key groove.

Abstract: A printing apparatus including a plurality of drive coils for driving printing hammers arranged longitudinally in side-by-side relation at one side of a core of the U-shape. A first cooling fluid passageway is defined inside the core of the U-shape to allow a cooling fluid for cooling the drive coils to flow therethrough, and a second cooling fluid passageway is defined outside the core by a duct to allow the cooling fluid for cooling the drive coils to flow therethrough without escaping to the outside by diffusion. A current of cooling fluid is forcibly fed into these cooling fluid passageways by a fluid machine.
