<p>The purpose of the present invention is to provide a method for producing a lithographic printing plate having excellent sensitivity and developability, which is capable of providing a lithographic printing plate having excellent printing durability, while suppressing odor of the developer liquid and development sludge due to the components removed by the development. This method for producing a lithographic printing plate is characterized by comprising: a step for forming a negative lithographic printing original plate that has a photopolymerizable photosensitive layer on a supporting body, said photopolymerizable photosensitive layer containing an acrylic polymer having a monomer unit derived from a vinyl carbazole compound and/or a urethane-acrylic hybrid polymer; a step for exposing the negative lithographic printing original plate in an image pattern; and a step for developing the thus-exposed negative lithographic printing original plate with a developer liquid that contains at least an organic solvent having a solubility in water of 1.5-7.0 g/100 ml at 20°C (component A), an amphoteric surfactant represented by formula (I) and/or formula (II) (component B), and water (component C).</p> |
