    Abstract: An electron-emitting device comprises a pair of oppositely disposed device electrodes and an electroconductive film electrically connecting the device electrodes and having an electron-emitting region formed as part thereof. The electroconductive film is partly or entirely covered by a metal oxide coat containing as principal ingredient with a melting point higher than that of the material of principal ingredient of the electroconductive film. The electroconductive film has also a deposited layer comprising carbon, a carbon compound or a mixture thereof.

    Abstract: A substrate for an electron source to be used for forming the electron source, the electron source and an image forming apparatus in which the substrate has been used, and manufacturing method thereof. The substrate to form the electron source in which an electron emission device is disposed includes a substrate containing Na, a first layer with SiO2 as a main component having been formed on the substrate, and a second layer containing electron conductive oxide. The electron source includes the substrate and the electron emission device disposed on the first layer or the second layer. The image forming apparatus includes the electron source and an image forming member to form an image with irradiation of electrons emitted from the electron source. According to a manufacturing method of the substrate for forming the electron source with which the electron emission device is formed, the first layer with SiO2 as its main component, and the second layer containing electron conductive oxide are formed on a substrate containing Na. The manufacturing method of an electron source includes a step in which the first layer with SiO2 as its main component, and the second layer containing electron conductive oxide are formed on a substrate containing Na, and a step of forming an electron emission device on the first layer or on the second layer.

    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.
