Abstract
The invention provides an infrared-sensitive positive-working image forming material which provides excellent development latitude, image formability and image region strength, and in which decrease in development property is prevented even when a certain time has passed after pattern exposure until development treatment; an infrared-sensitive positive-working planographic printing plate precursor which is formed from the image forming material and has excellent image formability and image region printing durability; and a method for manufacturing a planographic printing plate using the planographic printing plate precursor. The image forming material includes; on a support, a lower layer containing a polymer having carboxylic acid groups at side chains thereof, at least a part of the carboxylic acid groups forming a salt structure with a monovalent basic compound, and an infrared absorbing agent; and an upper layer whose solubility to aqueous alkaline solution is increased by heat, in this order.
