Abstract: A direct drawing type lithographic printing plate precursor comprising a water-resistant support having provided thereon an image receiving layer, wherein the image receiving layer comprises particles having rough surface composed of core particles having on the surfaces thereof fine particles adhered, and a binder resin comprising a complex composed of a resin containing a siloxane bond in which a silicon atom is connected with an oxygen atom and an organic polymer containing a group capable of forming a hydrogen bond with the resin containing a siloxane bond. According to the use of the direct drawing type lithographic printing plate precursor of the present invention, images free from not only background stain over an entire surface but also dot-like stain can be formed thereon. Also, the direct drawing type lithographic printing plate precursor can prepare a lithographic printing plate providing a great number of printed matter having clear images free from disappearance or distortion of image.
