An optical disc comprising a disc having a signal-recording layer, wherein a treated layer having a surface electric resistance of from 1x10<13> to 1x10<3> OMEGA is formed on the signal-recording layer, and the surface of the treated layer is subjected to electrophotographic printing. The optical disc can be desirably used as an optical disc, in which digital signals can be recorded, reproduced or erased, such as a digital audio disc, such as a compact disc, a video disc, or a CD-ROM.
