Claims

[Scope of claim for utility model registration] ■ The upper cover on which the upper roller for heat fixing is installed,
A lower roller for heat fixing is pivotally connected to the lower cover on which it is constructed, so as to be able to swing open and close around a pivot shaft parallel to the upper and lower rollers, which is disposed at one end in the front and rear direction. A pair of left and right arms are pivotally attached to the other end in the front-rear direction so as to be swingable around a support shaft parallel to the above-mentioned pivot shaft, and a horizontal shaft can be freely moved in the longitudinal direction of the arms between these two arms. springs are provided between both ends of the horizontal shaft and the corresponding arms for biasing the horizontal shaft toward the supporting shaft, while the left and right ends of the upper cover are provided with A recess into which the horizontal shaft is inserted is provided at the upper blade position of the support shaft, and by dropping the horizontal shaft into the recess, the upper and lower covers are connected in the closed position; A heat fixing device for an electrophotographic copying machine, characterized in that the upper and lower rollers are brought into pressure contact with each other by the biasing force of a spring. (2) The heat fixing device according to claim 0, wherein both arms are provided with biasing force adjusters for individually adjusting the biasing force of the spring.
