The littlest Higgs model with T parity has new flavor-changing couplings with the standard model quarks, which do not suffer strong constraints from electroweak precision data. So these flavor-changing interactions may enhance the cross sections of some flavor-changing neutral-current processes. In this work, we study the flavor-changing top-charm associated productions via the e{sup -}{gamma} collision at the ILC. We find that the cross sections are sensitive to the mirror quark masses. With reasonable values of the parameters, the cross sections may reach the detectable level and provide useful information about the relevant parameters in the littlest Higgs model with T parity, especially in setting an upper limit on the mirror quark masses.
