PROBLEM TO BE SOLVED: To provide the manufacturing method of an optical disk capable of obtaining an optical disk on which printings which are of high quality and have high-quality feeling are applied without generating an error in an information recording while without exerting an adverse influence on it. SOLUTION: This method is for obtaining an optical disk 1 in which an information recording disk 2 and a printed disk 3 in which prescribed printings are applied on a substrate for printing disk 30 are stuck. The method consists of a resistance adjusting process for adjusting the electric resistance of printing surface of the substrate for printing disk 30 to be <=1×10<14> Ω, a printed disk producing process for applying the prescribed printing or a printing surface 31' whose electric resistance is adjusted and producing the printed disk 3, by an electrophotographic process where a bias voltage is applied to the surface 31' with a contact type electrode and electrified toner on a transferring medium is transferred and a sticking process for sticking the information recording disk 2 and the printed disk 3 so that the recording surface 2a side of the information recording disk 2 and the printed surface side of the disk 3 are abutted. |
