An ion control method and apparatus in which positive ions and negative ions are generated by irradiating an X-ray in a particular space, and the ratio of positive and negative ions generated is controlled by changing the polarity and magnitude of the voltage applied to an electrode which is installed in the atmosphere of the positive and negative ions. Positive ions are adhered on the electrode by applying a negative voltage to the electrode, thus forming an environment with an excess of negative ions in the vicinity of the electrode; and the collecting of dust or removal of static electricity is performed by feeding the negative ions into the air or onto a static electricity charged object by a blower.
