Abstract:
A direct heat-sensitive recording device comprising:a light-fixing-type heat-sensitive recording material including a plurality of layers, said layers of said light-fixing-type heat-sensitive recording material including:a support;a heat-sensitive recording layer disposed on said support; andat least one light-fixing-type heat-sensitive recording layer, said light-fixing-type heat-sensitive recording layer being disposed on said heat-sensitive recording layer, said light-fixing-type heat-sensitive recording layer having heat recording sensitivities higher than a heat recording sensitivity of said heat-sensitive recording layer and which are fixed by electromagnetic waves of respectively different wavelengths,wherein each of said layers of said light-fixing type heat-sensitive recording material develops to a respectively different color, said direct heat-sensitive recording device comprising:exposing means for light-fixing image portions as undeveloped portions of each of said light-fixing-type heat-sensitive recording layers corresponding to respective colors by modulating light amounts of electromagnetic waves having respectively different wavelengths and illuminating the electromagnetic waves onto said light-fixing-type heat-sensitive recording layer; andheat recording means for developing image portions of said heat-sensitive recording layer and developing said undeveloped portions of said light-fixing-type heat-sensitive recording layer by applying to said light-fixing-type heat-sensitive recording material heat energy needed to develop said heat-sensitive recording layer.
