A thermal image transfer process uses an image receiving sheet. The process comprises imagewise heating a heat-sensitive sheet containing a wax to transfer the wax from the heat-sensitive sheet to the image receiving sheet. The image receiving sheet comprises a support and an image receiving layer provided thereon. The image receiving layer contains a polyolefin resin as a binder. In the process of the present invention, the image receiving layer further contains hydrophobic particles having an average particle size in the range of 2 .mu.m to 15 .mu.m. A conductive layer is preferably provided between the support and the image receiving layer. The conductive layer contains conductive oxide particles having an average particle size of not more than 0.5 .mu.m. The surface resistance of the conductive layer is not more than 10.sup.13 .OMEGA..
