Abstract: An object of the present invention is to provide a lithographic printing plate precursor which has excellent on-press developability and is capable of suppressing generation of slip stains and from which a lithographic printing plate with satisfactory printing durability is obtained, and a method of producing a lithographic printing plate and a printing method using the lithographic printing plate precursor. The lithographic printing plate precursor of the present invention is a lithographic printing plate precursor including an aluminum support, and an image recording layer, in which the aluminum support includes an aluminum plate and an anodized aluminum film disposed on the aluminum plate, the anodized film is positioned on a side of the image recording layer with respect to the aluminum plate, the anodized film has micropores extending from a surface of the anodized film on the side of the image recording layer in a depth direction, the micropores have an opening ratio of 20% to 70%, a steepness a45 on the surface of the anodized film on the side of the image recording layer is in a range of 3% to 25%, and an arithmetic average roughness Ra on the surface of the anodized film on the side of the image recording layer is in a range of 0.25 to 0.60 μm.

Abstract: A presensitized plate having a long press life and excellent resistance to scum and corrosive micro-stains and capable of on-press development is provided. The presensitized plate includes a photosensitive layer containing (A) a sensitizing dye, (B) a polymerization initiator, (C) a polymerizable compound, and (D) a binder polymer; and a protective layer which are formed on a support in this order. The support is prepared from an aluminum alloy plate containing intermetallic compound particles with a circle equivalent diameter of 0.2 μm or more at a surface density of 35,000 pcs/mm2 or more and aluminum carbide particles with a maximum length of 1 μm or more in an amount of up to 30,000 pcs/g.
