Electron emission apparatus comprising electron-emitting devices, image forming apparatus and voltage application apparatus for applying voltage between electrodes
Abstract:
An electron emission apparatus can effectively suppress the adverse effect of electric discharges that can take place between the oppositely disposed electrodes of the apparatus to which a high voltage is applied by dividing the electrode adapted to have a higher electric potential into segments in order to reduce the electrostatic capacitance between the electrodes. In the case of an electron emission apparatus comprising electron-emitting devices, said plurality of electron-emitting devices are disposed such that the direction along which those that can be driven simultaneously are arranged is not parallel with the direction along which the electrode is divided into the electrode segments in order to reduce the variable range of the electric current that can flow in the segments.
