Abstract:
1. An image forming apparatus comprising: (A) a first substrate having a principal surface; (B) a second substrate having a principal surface, the principal surface of said second substrate being spaced apart from the principal surface of said first substrate by a space, and being disposed in opposing relationship with respect to the principal surface of said first substrate; (C) a plurality of electron emitting devices arranged on the principal surface of said first substrate; (D) an image forming member arranged on a portion of the principal surface of said second substrate and surrounded by a conductive film which is arranged on another portion of the principal surface of said second substrate and is to be supplied with a potential that is lower than a potential to be supplied to said image forming member, wherein said conductive film is spaced apart from said image forming member; and (E) a spacer disposed between the principal surfaces of said first and second substrates, wherein a length between each end of said spacer in a longitudinal direction of said spacer is greater than that of said image forming member in a same longitudinal direction, and each end of said spacer in the longitudinal direction is arranged outside of an area surrounded by the conductive film.
