摘要： Preventing the excessive supply of the release agent 51, and simultaneously preventing the dripping of the excessive release agent 51 when applying a release agent 51, in order to prevent the offset by the heat roll 41. In a fixing device 4 having a heater lamp 43 mounted as a heat source in the interior of a cored bar 31 of a heat roll 41, wherein the temperature is maintained to a heat-fixing temperature by controlling the electricity being supplied to the heater lamp 43, an application roll 54 is mounted so as to contact the heat roll 41 for a uniform application of a release agent 51, and an application member 53 for supplying and applying the release agent 51 to the application roll 54 is mounted so as to contact said application roll 54, while a blade 55 for limiting the release agent 51 being applied to the roll is mounted thereto. The application member 53 and the blade 55 are positioned so that the opposing end surfaces thereof are adjacent to each other. Thereby, the application region in the tip portion of the application member 53 is in a saturated state, and the excessive supply of the release agent 51 is limited, which leads to the stabilization of the supply quantity, and the prevention of generation of an excessive release agent 51a.

摘要： An ink jet head includes an orifice plate (6) having a plurality of orifices (1) disposed transversely at prescribed intervals, a vibrating plate (3) disposed parallel to orifice plate (6) and deformed by applying a potential difference perpendicularly to the direction of polarization, and a plurality of partitions (9) disposed between orifice plate (6) and vibrating plate (3) in the space between adjacent orifices (1), and the space surrounded by orifice (1), vibrating plate (3) and partition (9) defines a pressure chamber (2) to be filled with ink. Vibrating plate (3) is provided with a groove having a rectangular cross section in a region having relatively low field intensity when signal voltage is applied. In this structure, the electric capacitance of vibrating plate (3) is reduced without adversely affecting the electric field intensity, and the efficiency of deformation of vibrating plate (3) is increased.

摘要： A photoconductive layer is formed on the entire outer peripheral surface of a light transmissive drum, and a conductive layer is formed on the photoconductive layer and is made up of a plurality of strip-like conductive portions. Provided around the drum are a tank for storing thermo-melting ink, a blade which removes surplus ink on the outer peripheral surface of the drum, a drier for drying the ink filling the gaps between the conductive portions in the conductive layers, a platen roller which presses against the outer peripheral surface of the drum with a sheet of recording paper in between, and a light source which is provided inside the drum, facing the inner peripheral surface thereof. When the light source is selectively operated in accordance with image information, current is made to flow between the conductive portions in the conductive layer via the photoconductive layer at image recording areas, thus causing the ink filling the gap to be transferred to the recording paper.

摘要： An ink jet head (10), having a long life, capable of discharging ink with a strong force and at a high speed is provided at small size. A container (6) comprises a casing (5) and a nozzle plate (7) covering the upper surface of the casing (5) and having an ink discharge opening (7a). A buckling structure (1) is fixed at its both longitudinal ends to the bottom surface of the container (6) via an installing member (3) and its center portion can be deformed upward by buckling. A diaphragm (2) is positioned above the buckling structure (1) with a space therebetween and placed on an inner wall of the casing (5) with its periphery fixed thereto so as to liquid-tightly partition the inside of the container (6) into a space on the structure-provided side and an ink chamber and deformable upward. A connection member (4) connects the diaphragm (2) and the buckling structure (1) at their center. Electrode (1a, 1b) are provided at both end of the buckling structure (1) to generate thermal stress therein by supplying electric current for buckling and consequently to apply pressure to ink (100) in the ink chamber for discharging.
