A process for making a lithographic printing plate, comprising: a step of preparing a negative-working lithographic printing plate precursor comprising a photopolymerizable photosensitive layer above a support; a step of imagewise exposing the negative-working lithographic printing plate precursor; and a step of developing the exposed negative-working lithographic printing plate precursor by means of a developer comprising at least a compound represented by Formula below as Component A, a compound represented by Formula below as Component B and water as Component C, wherein the photopolymerizable photosensitive layer comprises an acrylic polymer comprising a vinylcarbazole compound-derived monomer unit or a urethane-acrylic hybrid polymer, wherein in the Formulae, R 1 denotes a straight-chain or branched alkyl group having 4 to 8 carbons, preferably a n -butyl group, a n -hexyl group, or a 2-ethylhexyl group; R 2 and R 3 independently denote a hydrogen atom or a methyl group and when either one of R 2 and R 3 is a methyl group the other is a hydrogen atom, and R 2 and R 3 are preferably both hydrogen atoms; n denotes 1 or 2, preferably 1; R 4 denotes a substituted or unsubstituted phenyl group, 1-naphthyl group, or 2-naphthyl group, preferably a substituted or unsubstituted 1-naphthyl group or 2-naphthyl group, and m denotes an integer of 4 to 20, preferably 9 to 16. a step of preparing a negative-working lithographic printing plate precursor comprising a photopolymerizable photosensitive layer above a support; a step of imagewise exposing the negative-working lithographic printing plate precursor; and a step of developing the exposed negative-working lithographic printing plate precursor by means of a developer comprising at least a compound represented by Formula below as Component A, a compound represented by Formula below as Component B and water as Component C, wherein the photopolymerizable photosensitive layer comprises an acrylic polymer comprising a vinylcarbazole compound-derived monomer unit or a urethane-acrylic hybrid polymer, wherein in the Formulae, R 1 denotes a straight-chain or branched alkyl group having 4 to 8 carbons, preferably a n -butyl group, a n -hexyl group, or a 2-ethylhexyl group; R 2 and R 3 independently denote a hydrogen atom or a methyl group and when either one of R 2 and R 3 is a methyl group the other is a hydrogen atom, and R 2 and R 3 are preferably both hydrogen atoms; n denotes 1 or 2, preferably 1; R 4 denotes a substituted or unsubstituted phenyl group, 1-naphthyl group, or 2-naphthyl group, preferably a substituted or unsubstituted 1-naphthyl group or 2-naphthyl group, and m denotes an integer of 4 to 20, preferably 9 to 16.
