摘要:
In a fixing device, a controller switches a pressing member between a pressure application state to contact the pressing member against a fixing member and a pressure release state to separate the pressing member from the fixing member. The controller starts rotation of the pressing member before the pressing member contacts the fixing member in the pressure application state, when the pressing member switches from the pressure release state to the pressure application state. An oil applier includes an oil pan and an oil regulating member. The oil pan is provided under the pressing member to contain oil in which the pressing member is dipped. The oil regulating member is provided downstream from the oil pan in a direction of rotation of the pressing member to contact the pressing member to regulate an amount of oil adhering to the pressing member.

In a heat displacing type die adapted to extrude a sheet of molten resin, a heat displacing unit provided with a heater is secured to an upper die block. A lip gap is defined between a flexible lid and a stationary lip respectively provided for the upper and lower die blocks. The lower end of a bolt extending through the heat displacing unit is normally in contact with or secured to the flexible lip while the upper end is secured to the upper portion of the heat displacing unit. In a modified embodiment the bolt is air cooled.
