Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a black color developing heat-sensitive recording medium, which has an easily formable monolayer structure and in which perfect fixation by light is possible after thermal recording. SOLUTION: The photofixing type heat-sensitive recording medium is produced by applying mixed dispersion of diazonium salt involved in a microcapsule, a coupler and an organic base 26 on a support 21 and drying it. The diazonium salt consists of 4-morpholino-2,5-dibutoxybenzene diazonium salt. The coupler consists of a first coupler 23 made of naphthol AS, a second coupler 24 made of 3-methyl-l-phenyl-5-pyrazolone and a third coupler 25 made of naphthol AS-G.
