Patent ID: 7224113

Claim:
An image forming apparatus comprising, within an envelope: an electron-source substrate having a plurality of electron emitting elements; 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 said electron-source substrate and said acceleration electrode; a plurality of wiring portions for driving the electron emitting elements, formed on said electron-source substrate; and an electron-trajectory correcting electrode for deflecting a trajectory of an electron emitted from an electron emitting element closest to said spacer so as to be separated from said spacer, wherein said plurality of wiring portions are comprised of a wiring portion on which said spacer is disposed and a wiring portion on which said spacer is not disposed, and said electron-trajectory correcting electrode is disposed on the wiring portion on which said spacer is disposed and in a state of being separated from said spacer.
