PROBLEM TO BE SOLVED: To completely and uniformly execute erasing of an image in a wide width temperature range by adding a specific compound as an achromatization accelerator by using a compound represented by the specific formula as a reversible developer in a reversible heat-sensitive recording material. SOLUTION: In the reversible heat-sensitive recording material containing a dye precursor and a reversible developer for generating a reversible color tone change in the precursor according to a difference of cooling speeds after heating on a support, as the developer, at least one type of compounds represented by formulae I to III is used, and as an achromatization accelerator, at least one type of a compound represented by formula IV is contained, wherein m, q and r are ach 1 to 3, n is 0 or 1, R1, R3 and R5 are each 1-18C bivalent hydrocarbon group, R2, R4 and R6 are each 1-14C hydrocarbon group, X, Z, Q and T are each a bivalent group having at least one or above-CONH- bond in the formulae I to III, and R2 to R9 are each an alkyl group, an aralkyl group or the like, and R10 is 6-24C hydrocarbon group. |
