The charge ordered state in Yb4As3 has been studied by a resonant x-ray scattering (RXS) technique near the Yb L3-edge. The anomalous scattering factors, f' and f'', of Yb3+ and Yb2+ have been determined using the absorption spectrum of the Yb4As3. Based on the anomalous scattering factors, the valences of the two inequivalent Yb sites, +2 25 -{delta} and +2 25 + 3{delta}, have been evaluated by the RXS intensity corresponding to the charge ordering. The fully charge ordered state of {delta} = 0 25 {+-} 0 02 was elucidated.
