ABSTRACT:
In an image forming apparatus including an electron-source substrate having a plurality of cold-cathode electron emitting elements, each having an electron emitting portion and a pair of element electrodes, an acceleration electrode for applying an acceleration voltage operating on electrons emitted from the electron emitting elements, disposed so as to face the electron emitting elements, a spacer disposed between the electron-source substrate and the acceleration electrode, a wiring portion formed on the electron-source substrate for driving the electron emitting elements, these components being accommodated within an envelope, an electron-trajectory correcting electrode for correcting beam deviation due to charging of the spacer is provided near an electron emitting element near the spacer.
