    摘要： In an electron beam apparatus comprising an enclosure in which an electron-emitting device having an electron-emitting region between opposite electrodes is disposed, the electron-emitting device exhibits such a characteristic as that an emission current is uniquely determined with respect to a device voltage. The interior of the enclosure is maintained under an atmosphere effective to prevent structural changes of the electron-emitting device. An image-forming apparatus comprises an enclosure in which an electron source and an image-forming member are disposed, the electron source comprising the above electron-emitting device. An emission current is stable with a very small change in the amount of electrons emitted, a sharp image is produced with high contrast, and gradation control is easily carried out.

    摘要： In an electron source comprising a base plate and an electron emitting element disposed on the base plate, the electron emitting element includes a plurality of electron emitting portions electrically connected in parallel, the electrical connection being made through a thermally cut-off member. After forming the plurality of electron emitting portions, their electron emission characteristics are checked and, for that electron emitting portion on which the electron emission characteristic has been found not normal, the electrical connection is cut off. Alternatively, the electron emitting element includes an electron emitting portion connected to a voltage supply through a thermally cut-off member, and an electron emitting portion forming film which includes a thermally connecting member. In this case, after cutting off the electrical connection in that electron emitting portion on which the electron emission characteristic has been found not normal, the electron emitting portion forming film is connected to the voltage supply for forming another electron emitting portion in the film. With such an electron source and an image forming device using the electron source, a production yield and image quality are improved.
