Abstract
An image-forming apparatus comprising an envelope formed of a plurality of members, an electron source arranged within the envelope and an image forming member for forming images by irradiation of electron beams from the electron source is manufactured by heating the plurality of members to bond them together to produce the envelope in an atmosphere containing at least a gas selected from reducing gases, inert gases and non-reducing and non-oxidizing gases or in a vacuum. The electron source comprises preferably an electron-emitting element having a thin film for electron emission arranged between a pair of electrodes.
