Title: Fixing device
Inventor: KAJI KEIGO
IPC: G03G15/20
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce a cost, to shorten waiting time, to eliminate maintenance and to save electric power as for a fixing device. SOLUTION: The waiting time can be shortened by thinning the mandrel 2 of a fixing roller 1 to be <=1 mm and making heat capacity small. By arranging a thermistor 9 detecting the surface temperature of the roller 1 in an area where a paper is not passed, an image is prevented from being soiled by toner or paper powder attached to the thermistor 9. By making a good heat conductive heat radiation roller 11 abut on the roller 5 across an area where the paper is passed and the area where the paper is not passed, temperature difference between the area where the paper is passed and the area where the paper is not passed is reduced.
