Abstract
A method for producing an image-forming apparatus, the image-forming apparatus comprises a container, an electron-emitting device disposed in the container and has an electron-emitting section between a pair of electrodes, the electron-emitting device being adapted to emit electrons with application of a voltage between the pair of electrodes, and an image-forming member for forming an image by irradiation of the electrons emitted from the electron-emitting device, the production method having a step of irradiating the image-forming member with electrons emitted from the electron-emitting device, wherein the electrons to irradiate the image-forming member are electrons emitted by applying to the electron-emitting device the voltage of an opposite polarity to that of a voltage applied between the pair of electrodes of the electron-emitting device during driving for image formation of the image-forming apparatus.
