We measure the spectrum of cosmic rays with energies greater than $10^{18.2}$eV with the Fluorescence Detectors (FDs) and the Surface Detectors (SDs) of theTelescope Array Experiment using the data taken in our first 2.3-yearobservation from May 27 2008 to September 7 2010. A hybrid air showerreconstruction technique is employed to improve accuracies in determination ofarrival directions and primary energies of cosmic rays using both FD and SDdata. The energy spectrum presented here is in agreement with our previouslypublished spectra and the HiRes results.
