Abstract: An electron-emitting device includes a substrate (1), first and second carbon films (10) disposed so as to have a first gap (7) between the first and second carbon films on a surface of the substrate, and first and second electrodes (3,4) electrically connected with the first and the second carbon films respectively, wherein the carbon film has a region showing orientation, and a direction of the orientation is in an approximately parallel direction along the substrate surface. Thereby, it is possible to improve thermal and chemical stability of a carbon film and stabilize good electron emission characteristics over a long period.

Abstract: There is provided an electron-emitting device with high electron emission efficiency and with stable electron emission characteristics over a long period. The electron-emitting device has a substrate (1), first and second carbon films (21b,21a) laid with a first gap (8) in between on the surface of the substrate (1), and first and second electrodes (4b,4a) electrically connected to the first carbon film (21b) and to the second carbon film (21a), respectively. In the electron-emitting device, the distal portion (B) of the first carbon film (21B) is located above the surface of the substrate (1) at a greater distance (Hb) than the distance (Ha) of the distal portion (A) of the second carbon film (21a) above the surface of the substrate (1). In use, to effect electron emission, a higher potential is applied to the first electrode (4b) than to the second electrode (4a). An electron source is provided having a multiplicity of these devices on a common substrate (1). Such an electron source is provided in image forming apparatus opposite to an image forming member.
