摘要

An image forming material and an image forming method which are capable of accommodating a direct laser drawing method, producing an image of a high resolution easily and performing an image forming operation easily in a bright room, lithographic printing plate manufacturing method and apparatus, a lithographic printing plate making method, and a printed wiring board manufacturing method are provided. Concretely speaking, an image forming material having a layer of thermally meltable fine particles on a base material, and a method of forming an image on a base material by melt-fixing the portion of a layer of the thermally meltable fine particles of the image forming material which corresponds to an image portion, and then removing the portion of the layer of thermally meltable fine paticles which corresponds to a non-image portion are provided. The layer of thermally meltable fine particles can be melt-fixed by a laser. The removing of the non-image portion of the layer of thermally meltable fine particles can be done more easily by providing a layer of an alkali-soluble resin between the base material and the layer of thermally meltable fine particles, and applying an alkali solution to this layer of an alkali-soluble resin.
