    • A substantially ring-shaped seat section (8) protrudes from an inner circumference wall in a through hole (4) of a container attaching section (6) made of a metal. On an outer circumference of an electrode shaft (3) held in the through hole (4) through an insulator (5) made of a synthetic resin, locking protrusions (13, 14), which have a diameter larger than a hole diameter of the seat section (8), are provided at a distance from the seat section (8), on at least inner side or outer side of the seat section (8) in a shaft direction of the electrode shaft (3). Thus, for instance, when the inside of the metal container (2) is at a high temperature, the insulator (5) is destroyed and the electrode shaft (3) is to jump out from the container attaching section (6) to the outside or the inside of the metal container (2), the locking protrusions (13, 14) lock the seat section (8) and prevent the electrode shaft (3) from jumping out. Furthermore, since a space provided between the electrode shaft (3) and the container attaching section (6) due to the destruction of the insulator (5) is covered by having the locking protrusions (13, 14) lock the seat section (8), leakage of a liquid in the metal container (2) can be suppressed to minimum even the insulator (5) is destroyed.
    • 大致环状的座部(8)从由金属制的容器安装部(6)的通孔(4)的内周壁突出。 在通过由合成树脂制成的绝缘体(5)保持在通孔(4)中的电极轴(3)的外周上,具有大于孔径的直径的锁定突起(13,14) 座部分(8)在电极轴(3)的轴向方向上至少在座部(8)的内侧或外侧处设置在座部(8)的一定距离处。 因此,例如,当金属容器(2)的内部处于高温时,绝缘体(5)被破坏,电极轴(3)从容器安装部(6)跳出到外部 或金属容器(2)的内部,锁定突起(13,14)锁定座部(8),并防止电极轴(3)跳出。 此外,由于通过使锁定突起(13,14)锁定座部(8)而覆盖由于绝缘体(5)的破坏而在电极轴(3)和容器安装部(6)之间设置的空间, 即使绝缘体(5)被破坏,金属容器(2)中的液体的泄漏也可以被抑制到最小。

    • An image forming apparatus including a fixing device that has a rotatable endless belt, a contacting member to contact the rotatable endless belt, a rotatable pressing member contacting the contacting member via the rotatable endless belt to form a nip region, a heating member to heat the rotatable endless belt, a detecting device to detect a temperature of the heating member, a controlling device to control a temperature of the heating member based on a detection result of the detecting device, and a determining device to determine that the sheet-like recording medium has passed through the fixing device. The controlling device controls such that the temperature of the heating member set for the fixing operation is decreased to a temperature set when the sheet-like recording medium has passed through the fixing device, immediately after a last sheet-like recording medium in a series of a job has passed through the fixing device.
