  Provided are a thermal fusion-type lithographic printing plate precursor in which the visibility is excellent, ablation during laser exposure is suppressed, and the contamination of dampening water and printing ink during on-machine development is suppressed by a lithographic printing plate precursor having a support and an image-recording layer, in which the image-recording layer is capable of forming an image by infrared laser exposure, a non-exposed portion of the image-recording layer is removable by at least one of dampening water and printing ink on a printer, and the image-recording layer contains (1) a color developing system in which a hue change generated by infrared laser exposure is Δa/Δb≥0.6 and (2) 70% by mass or more of a thermoplastic polymer particle with respect to a solid content of the image-recording layer and a plate-making method in which the thermal fusion-type lithographic printing plate precursor is used.
