摘要： A fixing device includes a stationary member, a roller, an endless belt, a pressure rotator, and a lubricant applicator. The endless belt is stretched over the stationary member and the roller. The pressure rotator is disposed opposite the stationary member via the endless belt to form a fixing nip between the pressure rotator and the endless belt on the stationary member. The lubricant applicator contacts the roller over an entire length of the roller in an axial direction of the roller. The lubricant applicator contacts an inner surface of the endless belt and has an axial length equal to or greater than an axial length of the stationary member.

摘要： A fixing device includes a substantially cylindrical metal member, a heater, an endless, flexible fixing member, a rotary pressing member, and a stationary member. The heater heats the metal member. The fixing member is disposed rotatable around the metal member. An inner circumferential surface of the fixing member is heated by the metal member to heat and fix a toner image. The rotary pressing member is disposed opposite the metal member and pressed against an outer circumferential surface of the fixing member to form a nip between the rotary pressing member and the fixing member through which a recording medium bearing the toner image passes. The stationary member is disposed in pressure contact with the inner circumferential surface of the fixing member, and has an opposing face opposing the rotary pressing member and having a curvature smaller than a curvature of the rotary pressing member.

摘要： A method for manufacturing a structural component includes a first step of attaching at least one conductive member to a surface of a base material made of a composite material and a second step of forming the base material by conducting electricity to part or the whole of the conductive member to generate heat and/or making an assembly of the structural component by conducting electricity to part or the whole of the conductive member to generate heat. Part or the whole of the conductive member contained in the structural component produced in the first and second steps serves as a member giving to the aircraft at least one of a lightning strike protection function, an anti-icing and deicing function and an electromagnetic interference shielding function.

摘要： In a fixing device, a nip formation member is provided inside a loop formed by a fixing member rotating in a predetermined direction of rotation. A pressing member is pressed against the nip formation member via the fixing member to form a nip between the fixing member and the pressing member through which a recording medium bearing a toner image passes. The fixing member and the pressing member rotate and convey the recording medium bearing the toner image through the nip. The heat conduction member faces an inner circumferential surface of the fixing member to guide the fixing member sliding over the heat conduction member and to transmit heat to the fixing member. The heat conduction member includes a plurality of convex portions provided on an outer circumferential surface of the heat conduction member and contacting the inner circumferential surface of the fixing member.
