Disclosed is a process for producing a lithographic printing plate using a lithographic printing plate precursor comprising a support having a volume resistivity of more than 1.times.10.sup.10 .OMEGA..cm, an electrically conductive layer provided on one surface of the support and having a volume resistivity of 1.times.10.sup.5 .OMEGA..cm or less and a photoconductive layer provided on the electrically conductive layer and containing zinc oxide and a binder, the process comprising applying negative corona discharge to the lithographic printing plate precursor from the photoconductive layer side and at this discharging, contacting an electric conductor having an earth potential at least with the support of the lithographic printing plate precursor to electrically charging the photoconductive layer of the lithographic printing plate precursor.
