20080299483 | Method for recycling an image-forming member - The present invention provides a method for recycling a spent image-forming member mounted inside an image-forming apparatus to reuse the image-forming member. In the method, the image-forming member is made of an elastomer before the image-forming member is recycled; and when a recycling work is performed, a surface of the image-forming member is not abraded, but irradiated with ultraviolet rays or ozone at least once to decompose or/and deteriorate a deposit which has attached to the surface thereof in a use thereof so that the deposit is removed from the surface thereof. | 12-04-2008 |
20100143008 | CONDUCTIVE ROLLER - The present invention provides a conductive roller having a toner transport part composed of a vulcanized rubber composition at least on an outermost layer thereof. The vulcanized rubber composition contains a rubber component (A), highly conductive carbon black (B) having a particle diameter not less than 18 nm and less than 80 nm, an inorganic filler (C) consisting of not less than one kind of a metal oxide selected from among a group of titanium oxide, alumina, and silica. A total of a content of the highly conductive carbon black (B) and a content of the inorganic filler (C) for 100 parts by mass of the rubber component (A) is not less than 10 parts by mass nor more than 60 parts by mass. | 06-10-2010 |
20100172675 | CONDUCTIVE ROLLER - The present invention provides a conductive roller whose outermost layer is made of a vulcanized rubber composition. The vulcanized rubber composition contains epichlorohydrin rubber and chloroprene rubber as a rubber component thereof and 0.2 to 5 parts by mass of each of a thiourea-based vulcanizing agent and a vulcanization retarder consisting of N-(cyclohexylthio)phthalimide for 100 parts by mass of the rubber component. | 07-08-2010 |
20110229202 | MEMBER FOR IMAGE FORMING DEVICE - Provided is a member for an image forming device. The member has a base material and a film on the surface of the base material. The film is formed to maintain the surface shape of the base material. The member is provided with the base material composed of rubber of a resin, and the metal film composed of a metal, metal oxide, metal carbide, metal nitride or metal sulfide. The metal film is a conductive film formed by ion-plating titanium, aluminum or the like. | 09-22-2011 |
