Abstract
A method of manufacturing an electron source having a plurality of surface-conduction electron-emitting devices arranged on a substrate in row and column directions includes the forming of electron emission portions of the plurality of surface-conduction electron-emitting devices. The forming is carried out by supplying current through the plurality of surface-conduction electron-emitting devices upon dividing them into a plurality of groups. An image forming apparatus passes a current through a plurality of electron sources, which are formed on a substrate and arrayed in the form of a matrix, in dependence upon an image signal, and an image is formed by a light emission in response to electrons emitted from the plurality of electron sources.
