The effects of ion temperature on the electron-dust collision process are investigated in complex dusty plasmas. The second-order eikonal method is employed to obtain the scattering phase and cross section for the electron-dust grain collision as functions of the impact parameter, collision energy, ion temperature, density, and Debye length. The results show that the eikonal scattering phase and eikonal electron-dust grain collision cross section decrease with decreasing ion temperature in dusty plasmas. It is also found that the effect of ion temperature on the electron-dust grain collision process is more significant than the effect of electron density in dusty plasmas. In addition, it is shown that the density effect is more significant when the electron temperature is comparable to the ion temperature.
