Within the framework of the fermion-spin theory based on the charge-spin separation, the charge dynamicsof the doped antiferromagnet on a triangular lattice is studied. The holon part is treated by using the loopexpansion to the second order. It is shown that the charge dynamics is mainly caused by charged holonsmoving in the background of spinon excitations. The optical conductivity spectrum shows an unusual behaviorat low energies and an anomalous midinfrared band, while the resistivity exhibits a nonlinearity intemperatures.
