The purpose of the present invention is to provide: a lithographic printing original plate for on-press development, which has excellent printing durability and on-press developability, and which is capable of suppressing dampening water contamination of an on-press developed image recording layer; a lithographic printing plate which is obtained using this lithographic printing original plate for on-press development; a plate making method for a lithographic printing plate; and a printing method. A lithographic printing original plate for on-press development according to the present invention is characterized by having, on a supporting body, a component A-containing layer which contains, as a component A, a polymerizable compound that is represented by one of formulae 1-4. It is preferable that the component A-containing layer is an image recording layer and the image recording layer contains, as a component B, a polymerization initiator. |
