Abstract
This invention relates to an electron source and an image forming apparatus each of which particularly comprises a surface conduction type electron emitting element as an electron emitting element, a method of manufacturing an electron source and an image forming apparatus, in which the energization forming treatment step of the surface conduction type electron emitting element is performed by applying a voltage to an electron emitting portion formation thin film via a nonlinear element connected in series with the thin film and having nonlinear voltage/current characteristics, an electron source and an image forming apparatus in each of which the nonlinear element is connected in series with the surface conduction type electron emitting element, and a method of driving the same.
