An electrophotographic copying machine has a device for fixing toner. The fixing device is constructed such that it has a base support with two pairs of locating holes for a pair of spaced apart lower end blocks having means to support bearings which rotatably support the lower fixing roller. There is an upper pressure roller which rests upon the lower roller. The upper roller is rotatably supported by bearings which are clamped downwards through engagement with "U" Bolts. In turn, the "U" Bolts are yieldably attached through the locating holes to the base support of the fixing unit. The "U" Bolts are threaded at the respective straight shanks, which allows for easy adjustment of the roller nip pressure through springs and adjusting nuts, engaged to the shanks of the "U" Bolts beneath the base support.
