A process for producing a lithographic printing plate which is inexpensive, is not elongated, can be readily handled and can provide a uniform image, is disclosed. The process comprises the steps of: using an original plate for lithographic printing comprising a support having a volume electric resistance of more than 1 x 10<10> OMEGA .cm, a conductive layer having a volume electric resistance of 1 x 10<5> OMEGA .cm or less, provided on one surface of the support, and a photoconductive layer containing zinc oxide and a binder, provided on the conductive layer, conducting negative corona discharge from the side of the photoconductive layer of the original plate for lithographic printing, and during this corona discharge, contacting a conductor having earth potential with at least the support of the original plate, thereby charging the photoconductive layer of the original plate for lithographic printing. |
