Alkaline sizing characteristics of TMP (thermomechanical pulp) handsheets with AKD (alkylketene dimer) were studied under various conditions. The sizing degree of TMP handsheet was much lower than that of chemical pulp. Especially, the sized TMP handsheet dried at $20^{\circ}C$ showed no sizing features, but sizing degree of TMP handsheet was clearly Increased by heat treatment at $105^{\circ}C$. The sizing effect of TMP was also improved by addition of $CaCO_3$, but it was not affected by pH. Therefore, sizing effect of TMP with AKD can be improved to some extent by controlling stock condition and heat treatment of handsheet.
