Characteristics adjustment method of image forming apparatus, manufacturing method of image forming apparatus and characteristics adjustment apparatus of image forming apparatus

Image Number 13 for United States Patent #7388561.

There is provided a characteristic adjustment method for an image forming apparatus that is provided with a multi-electron source in which a plurality of electron-emitting devices are electrically connected by wiring and arranged on a substrate and a fluorescent member for emitting light by irradiation of an electron beam, the method including: a measurement step of dividing a display portion of the image forming apparatus into a plurality of areas and measuring light emitting characteristics of at least one or more of the electron-emitting devices in the respective divided areas, and a shifting step of shifting the light emitting characteristics of the electron-emitting devices in the divided areas to individual characteristic target values by applying a characteristic shift voltage to the electron-emitting devices.
