Title: Fixing device
Inventor: TANIGAWARA SHINJI
IPC: G03G15/20
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To resolve a problem that the temp. of a nip part in paper nonpassing part areas is higher than that of a paper passing part area. SOLUTION: In the thermal roller fixing system fixing device for executing fixing in such a manner that a pressure roller 3 comes into press-contact with a fixing roller 2 heated to a uniform temp. and a body to be heated of a copying paper on which toner rides passes through the nip part. When the heated body has a small size, the temp. of the paper nonpassing areas rises with respect to the paper passing part area. For preventing this a radiator roller 6 is brought into press-contact with the fixing roller 2 to rotate the radiator roller 6 with the rotation of the fixing roller 2. The central part 6a through which the small- sized body to be heated passes of the radiator roller 6 is made of a material whose thermal conductivity is comparatively low and both end parts 7 of the paper nonpassing areas are made of a material whose thermal conductivity is comparatively high.  The radiator roller 6 is rotated in press-contact with the fixing roller 2, so that the temp. in the axial direction of the nip part is made uniform by the heat radiation of the temp. of the paper nonpassing regions which is made higher than that of the paper passing region.
