Patent ID: 7548017

Claim:
An image forming apparatus comprising: a face plate which has a luminescent member and an electrode, the luminescent member emitting light by electron irradiation, the electrode being defined by a first potential; a rear plate which has a wiring extending in a first direction and a plurality of electron-emitting devices arranged along the first direction and connected to the wiring, the wiring being defined by a second potential different from the first potential, and the plurality of electron-emitting devices irradiating the luminescent member with an electron; and a spacer arranged between the wiring and the electrode and electrically connected to the wiring and the electrode, the spacer having an end face which faces the rear plate, the end face having a resistivity, and the spacer extending longitudinally along the first direction; wherein the end face of the spacer facing the rear plate includes contacting areas contacting the wiring and non-contacting areas spaced from the wiring, the contacting areas and the non-contacting areas being arranged in an interleaved relationship of abutting to each other along the first direction, and a fine particle film provided on at least the non-contacting areas of the wiring.
