Method and apparatus of manufacturing electron source, and adjusting method of the electron source, and method of manufacturing an image forming apparatus having the electron source

摘要

In an electron source manufacturing method and apparatus, a plurality of electron-emitting devices are commonly connected to a first wiring and to a plurality of second wirings, respectively. A voltage V1 is applied to the plurality of devices connected to the first wiring by the difference between potentials applied to the first wiring and the plurality of second wirings. The voltage V1 has a relationship with a maximum value V2 of a voltage applied as a normal driving voltage after the voltage application step, so as to satisfy: giving a current I flowing upon application of the voltage V when a voltage V falling within a voltage range causing electron emission upon application of the voltage between the two electrodes of each device is applied to the device:and letting f'(V) be the differential coefficient of f(V) at the voltage V,a condition:In this manner, the potential applied to each second wiring is set to reduce the difference in magnitude of the voltage V1 applied to each device connected to the first wiring.
