ABSTRACT:
In an ion generating element, (i) an induction electrode and a heater electrode are provided away from each other on one surface of an insulating base material such that the induction electrode and the heater electrode are insulated from each other, (ii) a dielectric layer is provided on the surface of the insulating base material, and (iii) the dielectric layer has a length covering the insulating base material and the dielectric layer has openings above a ground terminal of the induction electrode and above a ground terminal and a power supply connection terminal of the heater electrode so that the terminals are exposed. As a result, it is possible to provide an ion generating element for generating ions along with creeping discharge, a charging device, and an image forming apparatus, each of which can be produced at low costs and prevent damages when unexpected troubles occur, and each of which is excellent in terms of safety.
