Fixing rotatable member for heat fixing device and fixing device using the same
Abstract:
The heat fixing device includes a heating roller and a pressure roller disposed in contact with the heating roller, the heating roller includes a base member and a surface layer, and the surface layer has a surface resistivity of 1×1016 &OHgr; or lower, and a residual elongation percentage of 3% or lower. By this arrangement, charging of the heating roller can be prevented so that the recording medium can be prevented from being curled around the heating roller.
Abstract(Chinese):

热定影装置包括加热辊和与加热辊接触设置的加压辊，加热辊包括基底部件和表面层，表面层的表面电阻率为1×10 16Ω或更小，残余伸长率 百分比为3％以下。 通过这种布置，可以防止加热辊的充电，从而可以防止记录介质在加热辊周围卷曲。
