A reversible thermosensitive recording material which includes a support, and a thermosensitive layer provided on the support and including, as main ingredients, a resin matrix and an organic low molecular weight substance dispersed in the resin matrix, wherein the transparency of the thermosensitive layer reversibly changes depending on the temperature thereof is characterized in that the rate of change in heating temperature for the initiation of transparentization is 13% or less, the rate of change in transparency is at least 50% or the rate of change in film thickness is at least 2%. By heating the reversible thermosensitive recording material, the formation and erasure of images may be suitably effected.
