In this paper, we report on the study of the temperature dependence of Fe L $_{3}$ -edge X-ray absorption spectra (XAS) of LuFe $_{2}$ O $_{4}$ . In the charge ordered state the valence of Fe is in Fe $^{2+}$ and Fe $^{3+}$ . And the Fe L $_{3}$ -edge XAS spectra have double peak structure which is attributed the Fe $^{2+}$ and Fe $^{3+}$ state. In high temperature, the double peak structure becomes indistinct because the thermal excited state overlaps while the Fe valence keeping the integer number.
