An electrostatic charge regulator capable of holding an electric charge in a stable state and superior in environmental stability, as well as a method for making the electrostatic charger regulator and an image forming method using the electrostatic charge regulator, are disclosed. The electrostatic charge regulator has a surface layer containing a non-linear resistor on a base member such as a carrier, a developer sleeve, a developer blade, or a transfer belt. The electrostatic charge regulator is obtained by forming on the base member a surface layer by using a thin film of a composite metal oxide or by using dispersion of powder of the composite metal oxide in a high molecular compound, the composite metal oxide being prepared using at least one metal selected from Group A metals (Zn, Ti, Si, Al, Zr) and at least one metal selected from Group B metals (Bi, Sb, C, Y, La, Pr, Sc, Ce, Sn, Pb). The image forming method uses the above electrostatic charge regulator to form an image.
