摘要： A multi-nozzle ink jet head formed through semiconductor processes is disclosed. The multi-nozzle head has a head substrate (28) in which are formed a plurality of nozzles (27) and a plurality of pressure chambers (26), a diaphragm (40) that acts as a common electrode and covers the plurality of pressure chambers (26), piezoelectric body layers (41) that are provided in correspondence with the pressure chambers (26) on the diaphragm (40), and individual electrode layers (42) that are provided on the piezoelectric body layers and have individual electrode parts (42-3) corresponding to the pressure chambers and wiring parts (42-1, 42-2) for the individual electrode parts. By interposing a low-dielectric-constant layer or an insulating layer in the region of the wiring parts, or not disposing the common electrode in the region of the wiring parts, the electrical capacitance of the driving parts is reduced, and hence a driving lag is prevented from occurring, and moreover unwanted vibration of the piezoelectric bodies is prevented.

摘要： A printer having a plurality of nozzles each for discharging ink supplied from an ink supply part (50) comprises a head main body (3) including a plurality of pressure chambers each provided for each of the nozzles and filled up with ink, a plurality of pressurizers each provided for each of the pressure chambers for pressurizing the pressure chamber to discharge the ink in the pressure chamber through the nozzle and ink supply passages for supplying the ink from the ink supply part (50) to the plurality of pressure chambers, and a joint section (8) protruded from the head main body (3) for joining the ink supply part (50) to the head main body (3). The head main body (3) is formed on a substrate, and the substrate is partially removed from the head main body (3) so that a common ink passage is formed in the substrate for making communications between the ink supply passages and ink supply ports (51) of the ink supply part (50) while the joint section (8) is formed as a residual portion of the substrate on the head main body (3). This improves the degree of integration of an ink jet head to achieve the size reduction of the ink jet head, and enhances the rigidity thereof.

摘要： A color picture image formation device includes a plurality of photosensitive body drums and a plurality of image formation sections each consisting of a charge unit, an exposure unit and a plurality of developing units for developing toner picture images of various colors and an intermediate transfer body for holding the toner powder images of required number of colors, which transfers the toner picture images to the recording paper and fixes them thereon by a fixing unit after all the toner picture images have been formed on the intermediate transfer body. A transfer voltage is applied by the intermediate transfer body for every developing unit. The intermediate transfer body is a drum formed as a multiple layer structure including a metallic tube, an insulation layer, a metallic conductive electrode which is split into a plurality of sections, and a voltage application layer on the surface of the metallic tube. A transfer roller transfers the toner-picture images onto the recording paper. A voltage application brush which comes into contact with the sections of the metallic conductive electrode applies voltage to the intermediate transfer body.
