摘要:
A carrier or substrate for a photoconductor to be used for the formation of an electrophotographic recording element, particularly an imaging drum for an electrophotographic printing press, wherein the carrier is made of a metal or a metal alloy, preferably of aluminum, is prepared wherein the surface of the carrier supporting the photoconductor, used to form a barrier layer, is oxidized, preferably by etching and/or anodizing. The oxidized surface of the barrier layer is sealed with a sealing material following oxidation, and a preservative or impregnating agent is used as the sealing material.
摘要:
The present invention relates to a toner and process for preparing a toner for reproduction of a metallic, preferably golden or silvery, hue by a printing process, especially for electrophotography. A congeneric process and/or a congeneric toner is preserved with regard to its metallic hue and at the same time not to impair the essential properties of the toner for the printing process in which it is to be used. At least one metallic pigment is provided with a coating of silicate and subsequently with an organic layer and combining the thus obtained particle with toner material.
摘要:
A separating agent, in particular silicon oil, applied to the surface of a fuser mechanism, preferably in an electrophotographic printing machine. Contamination of the surfaces of the printing media is substantially prevented or reduced when the separating agent is diluted with at least one solvent with a boiling point equal to or greater than 60° C., preferably equal to or greater than 100° C., but below 160° C.

A method for producing an antenna structure for an RFID device, a dry toner for use in producing an antenna for an RFID device and a RFID device comprising an antenna structure made of fused toner are disclosed. In a method for producing an antenna structure for an RFID device, a dry toner comprising a polymeric binder and metallic particles is provided. The toner comprises particles having a resistance allowing triboelectric charging or a resistance allowing inductive charging, wherein said metallic particles are nanoparticles having a mean particle size below approximately 500 nm in at least one direction. In the method, a continuous layer of the dry toner is applied to a substrate in a desired shape of an antenna via an electrophotographic printing process, and subsequently the toner is fused to the substrate by heating the toner above its glass transformation temperature. The dry toner for use in producing an antenna for an RFID device comprises toner particles having a resistance allowing triboelectric charging or a resistance allowing inductive charging. The toner particles comprise a polymeric binder and metallic particles, wherein said metallic particles are nanoparticles having a mean particle size below approximately 500 nm in at least one direction.
摘要:
Sheets are bound to form a bound document by fastening together the sheets and a binding strip. A spacer is applied to a back sheet adjacent to the feet of the fasteners. A wraparound portion of the binding strip is folded around the spine edges of the sheets so that adhesive on the strip contacts the spacer or the back sheet farther from the spine than the feet of the fasteners. The adhesive is affixed to the back sheet. The binding strip includes a spacer adjacent to the heads of the fasteners, protruding above the face-attachment portion at least as far as the heads of the fasteners do.

摘要:
A microwave fuser apparatus, for a reproduction apparatus, the microwave fuser apparatus having at least two microwave applicators, staggered relative to a receiver member transport path with an area of overlap, for applying microwave energy to a receiver member traveling on such transport path relative to the microwave applicators to have toner images fused thereto. The microwave fuser apparatus has at least one additional microwave applicator, located adjacent to the overlapping area between the at least two staggered microwave applicators that applies microwave energy to the receiver member. The at least one additional microwave applicator effectively maintains an elevated temperature of a receiver member.
