Abstract
A method of manufacturing an electron-emitting device having excellent electron emission characteristics is provided in which fibers comprising carbon as the main composition are fixed (bonded) to a substrate in a desired area and at a desired density with simple processes and inexpensive manufacture cost, and a manufacture method for an electron source, a light-emitting apparatus and an image forming apparatus using such electron-emitting devices is provided. A method of manufacturing an electron-emitting device made of material comprising carbon as main composition by an aerosol type gas deposition method in which the material comprising carbon as the main composition is aerosolized and transported together with gas, and tightly attached (bonded) to a substrate via a nozzle.
