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： The invention provides an ink jet head which exhibits a good response characteristic through heating and fast cooling enough to implement high-speed printing. A nozzle plate (10) having a nozzle orifice (11), and a substrate (7) constitute part of a peripheral wall of an ink chamber (31). A pressure generating member (20) is provided in the ink chamber (31). The pressure generating member (20) has a buckling member (1), a heater layer (3), and a diaphragm (5). The buckling member (1) is formed into a generally plate shape and its peripheral portion is attached to the substrate (7). The buckling member (1) can be switched between a no-displacement state in which it undergoes substantially no thermal stress, and a buckled state in which it is thermally expanded and buckled. The heater layer (3) is provided along a surface of the buckling member (1) on the substrate (7) side. The diaphragm (5) is composed of a generally plate-shaped flexible material and provided along a surface of the buckling member (1) on the nozzle plate (10) side in such a state that at least its peripheral portion (5c) is attached to a peripheral portion (1c) of the buckling member (1).
