Claims

[Claims for Utility Model Registration] (1) In a thermal roller fixing device that fuses and fixes a powder image on a transfer material using a pair of rollers, at least one of which has a heat source, the rollers are not normally in contact with each other; A fixing device comprising a cleaning member that comes into contact with the roller and removes dirt on the roller only during jam processing. (2) The fixing device performs actions required for jam processing, such as opening and closing the main body of the electrostatic recording device that incorporates the fixing device, opening and closing the main body cover, opening and closing the paper output port of the fixing device, etc. 2. The fixing device according to claim 1, which has a mechanism for bringing a cleaning member into and out of contact with the roller, and wherein the cleaning member comes into contact with the roller only during jam processing. (3) In the fixing device, the cleaning member, which normally comes into contact with the roller to detect and control the surface temperature of the roller, is activated at the same time as the cleaning member, which comes into contact with the roller only during jam processing, contacts the roller. The fixing device according to claim 1 of the utility model registration claim, characterized in that the fixing device is spaced further apart.
