    Abstract: A lithographic printing plate precursor includes: a support having a surface, a contact angle of water droplet in air on which is 70° or more; and a photosensitive layer, wherein the support has, on a surface of the support, a compound having a functional group X, the functional group X is a functional group capable of forming a chemical bond with a compound having a functional group Y which can interact with the functional group X, when the functional group X is brought into contact with the compound having a functional group Y, to adsorb the compound having a functional group Y on the surface of the support so as to decrease the contact angle of water droplet in air on the surface of the support to 30° or less.
