Abstract: A thermal transfer sheet is used in indirect transfer printing for forming an image through a primary transfer from the thermal transfer sheet to an intermediate transfer medium and thereafter forming an image on a transfer target through secondary transfer to the transfer target. The thermal transfer sheet includes, on a substrate, a masking layer that is a portion that prevents transfer to the transfer target during the secondary transfer. The masking layer is formed from a resin having a Tg of 140° C. or more and 220° C. or less, and the masking layer contains 0.5 wt % or more and 20 wt % or less filler particles relative to the resin.
