  • Printing method, printer, printed object, and optical disk
    Patent number: 6146805
    Abstract: The present invention aims at satisfactorily printing such as labels by electrophotographic process onto a surface to be printed of an object such as synthetic resin plates such as optical disks. When printing the surface to be printed of the object by transference of charged toner on a transfer medium onto the surface to be printed, an electric charge is supplied to the surface to be printed, by contacting an electrode connected to a power supply device with the surface to be printed, in the vicinity of a transfer position where the toner on the transfer medium is transferred onto the surface to be printed. The surface electric resistance of the surface to be printed of the object is adjusted to be equal to or less than 1.times.10.sup.14 .OMEGA., in advance of the transfer of the toner.
