We report X-ray diffraction measurements of the charge-ordered organic conductor θ-(BEDT-TTF)2CsZn(SCN)4 at various temperatures with external currents. The two kinds of diffuse scattering observed at q1=(2/3k1/3) and q2=(0k1/2) exhibit remarkable difference in the interplane correlation along the b-axis, the temperature dependence, and the electric-current dependence. These observations suggest that the two diffuse scatterings come from spatially different charge-ordered domains. The external current melts the q2-type domains, which can control the competition of the two orders.
