PROBLEM TO BE SOLVED: To obtain an image forming material adapted to manufacture of a master without basis of removal of a silicone layer by providing a first layer containing carbon or organic absorptive compound and an ink non-sticky second layer, and removing the first layer on a non-exposure region without excessively removing the second layer. SOLUTION: A first layer containing more carbon or organic absorptive compound than 50 wt.% is applied onto an ink non-sticky second layer. The first layer is exposed as an image in a heat mode. Then, a printer is started, and the first layer is removed in a non-exposure region without substantially removing the second layer. Here, a print master can receive an ink in the exposed region. Accordingly, image forming material can be used as a driographic printing master without treating step immediately after the exposure. Thus, the material adapted to manufacture of the master without basis of removal of a silicone layer is obtained. |
