Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a long-lived fixing unit by surely carrying a high- smoothness paper such as an OHP sheet and preventing the soiling of a pressure roller. SOLUTION: The surface toughness of a heating roller 1 is set to be Rmax<=2μm and uniform in a longitudinal direction, but the surface roughness of the pressure roller 2 is set to be Rmax<=2μm, that is, the same as that of the heating roller 1, in a part L1 in contact with the printing region of a paper sheet 12 and Rmax=10 only in both end parts including the nonprinting regions L2 of the paper. Since the surface of the pressure roller 2 in contact with the printing region is in the same surface state as that of the heating roller 1, offset toner stuck to the heating roller 1 is hardly transferred to the surface of the pressure roller 2.  Further, the heating roller 1 and the pressure roller 2 are rotated at the same circumferential speed by gears 23 and 24 and in the nonprinting region parts L2 as the end parts of the paper, the surface roughness of the pressure roller 2 is set to be Rmax=10μm, to greatly exert carrying force by the pressure roller 2.
