Abstract:
An image forming apparatus comprising:a rear substrate having an electron-emitting device; a front substrate having an image forming member; and a support member for maintaining an interval between said rear substrate and said front substrate, wherein said support member has insulating properties for maintaining a charge-up amount of said support member in a substantially stable state in driving said electron-emitting device, and comprises an electrode for applying a deflection force in a direction away from said support member to an electron emitted by said electron-emitting device, wherein said electrode is arranged on a portion of said support member near said rear substrate and is not arranged past a predetermined position on said support member, and wherein when a distance between said rear substrate and said front substrate is 0.5 mm to 10 mm, a size of a pixel formed on said front substrate upon reception of an emitted electron is 100 &mgr;m to 1 mm, and an accelerating voltage for accelerating an electron emitted by said electron-emitting device toward said image forming member is 1 to 15 kV, and the distance between said rear substrate and the predetermined position is not more than Â¼ of the distance between said rear substrate and said front substrate.
