摘要

An image forming material includes an image forming layer containing a water-insoluble and alkali-soluble resin, a light-heat converting agent and a compound represented by the following general formula (1). In general formula (1), R1 to R3 independently represent an organic group, where R1 represents a residue forming a ring containing a N1 atom, R2 and R3 may bond to each other to form a ring or at least one of R2 and R3 may bond to R1 to form a ring and X- represents a conjugate base of an organic acid or inorganic acid. The ring containing the N1 atom is preferably a piperidine ring.
