The present invention provides a fixing apparatus which effectively prevents a recording medium from coiling around the surface of a fixing member and also prevents damage to the surface of the fixing member, and an image forming apparatus comprising this fixing apparatus. A gap between the tip end of separating means and the fixing member can be managed appropriately, and as a result, the recording medium can be prevented from coiling around the surface of the fixing member.

In a liquid crystal display device, a thickness of a liquid crystal layer in each pixel is adjusted according to a display color (red, green, and blue). For example, by changing the thickness of the color filter corresponding to the display color according to the display color, a thickness (cell gap) of the liquid crystal layer in each pixel is set to a predetermined value corresponding to the transmittance of light in the liquid crystal. In order to maintain the cell gap at a constant value, heights of spacers formed above the color filters are set to values different from each other according to the thickness of the liquid crystal layer which differs for each display color. With this structure, the spacers substantially contribute to maintaining the gap in the pixel regions of different display colors in which the spacers are formed.
