A toner containing a colorant, a binder resin and a laminar inorganic mineral in which part or all of the ions present between layers are modified by organic ions. For this purpose, all light-conducting elements allocated to the sensors are to be connected in one piece as a light-conducting member and integrated into the light-conducting member of a rain sensor. The sidewall of outer disk has an outlet of the feed material. A guide member of the guiding device has a slot for receiving a bone resector and enabling accurate resection of bone around the joint. The first press member and the second press member press upper and lower surfaces of a workpiece accommodated in a press space that is formed between the first press member and the second press member, so as to produce a forged product.
