An ion generating device includes a controller, positive and negative ion generating circuits, an airflow generator, and a detecting element. The controller is preinstalled with a constant of proportionality, controls the positive and the negative ion generating circuits, and the airflow generator directs the ions to a destination. The detecting element detects the balanced voltage of the positive and negative ions at the destination, and responds with the detecting result to the controller. The controller increases or decreases the ion numbers. The variation of the ion numbers is x, and the balanced voltage at the destination is y. The controller compares the function of x and y with the constant of proportionality to determine whether they are similar. If the comparison result is similar, then the electrostatic dissipation capability of the ion generating device is normal.
