Disclosed is an electrically conductive member, comprising a substrate of a metal or a resin and an electrically conductive elastic layer formed to cover the substrate, wherein the electrically conductive elastic layer is formed of a rubber elastic body prepared by dispersing at least an electrically conductive powder used as a conductive agent into a rubber compound, followed by vulcanizing the rubber compound, the electrically conductive powder being obtained by curing and powdering an electrically conductive rubber compound or an electrically conductive resin mixture.

Electrically conductive member

Disclosed is a transfer-fixing belt for an electronic appliance, comprising a seamless reinforcing layer made of a continuous string, a heat resistant rubber layer formed on the reinforcing layer, and a heat resistant resin layer formed on the heat resistant rubber layer and adapted for releasing the toner attached thereto.

Fixing belt for an electrical appliance and method of manufacturing the same

Disclosed is a belt type fixing apparatus for thermally fixing an unfixed toner layer on a paper sheet. The fixing apparatus has a heating roll and a resilient endless belt stretched by a plurality of rolls such that the endless belt is partly pressed against a part on the circumferential outer surface of the heating roll to form a nipping portion. The heating roll having a hard, non-resilient surface has a mandrel, a halogen lamp arranged inside the mandrel and a release coating layer formed on the outer circumferential surface of the mandrel.

Belt nip-type toner fixing apparatus using elastic endless belt

Disclosed is a transfer belt for an electro-photographic apparatus, comprising a seamless reinforcing layer made of a continuous string, and a semi-conductive rubber layer formed on the reinforcing layer.

Transfer belt for electrophotographic apparatus and method of manufacturing the same

Disclosed is a conductive rubber roller, comprising a core metal shaft, an ionic conductive layer formed to surround the outer circumferential surface of the core metal shaft and consisting of a high molecular weight elastomer containing an ionic conducting agent or a foamed body of such a high molecular weight elastomer, an electron conductive layer formed to surround the outer circumferential surface of the ionic conductive layer and consisting of a high molecular weight cellular elastomer containing an electron conducting agent or a high molecular weight cellular elastomer containing an electron conducting agent, a toner contamination preventing layer formed to surround the outer circumferential surface of the electron conductive layer, and an insulating annular sealing member mounted to each of both edges of the ionic conductive layer and the electron conductive layer both extending in the longitudinal direction of the metal core wherein a relationship R,>R,>R,, where R,, R,and R,denote, respectively, the electric resistance of the ionic conductive layer, the electron conductive layer and the toner contamination preventing layer, is satisfied, and the annular sealing member has an electric resistance of at least 10,&OHgr;&middot;cm.

Conductive rubber roller

Disclosed is a printing apparatus comprising a driving roll, a supporting roll, an endless offset blanket stretched between the driving roll and the supporting roll, a plurality of plate cylinders for transferring inks having a plurality of different colors onto the endless offset blanket, a plurality of first impression drums arranged to have the endless offset blanket held between the first impression drums and the plate cylinders, ink supply means for supplying the inks of the plural colors to the plate cylinders, and a second impression drum positioned to push the supporting roll and to have a printing medium held between the supporting roll and the second impression drum, the inks of the plural colors transferred onto the endless offset blanket being printed on the printing medium in a single operation.
