構造。[Scope of Claim for Utility Model Registration] In a fixing roller mounting structure in which a pair of upper and lower rollers are rotatably supported on a frame and both rollers are brought into pressure contact, the shaft ends of both the upper and lower rollers are attached to the frame. a groove into which the frame is inserted and has an opening at the end of the frame;
Two levers are attached to the ends of the upper and lower rollers fitted in the grooves so as to be able to rotate together, and both ends are fixed to each of the two levers, and an elastic force is applied to each of the rollers in the pressure direction of the rollers. A fixing roller mounting structure comprising an elastic body that acts, and a stopper that restricts or frees the rotational movement of one lever at a position that closes an opening of a groove.
