Electron emitting element, method for producing electron emitting element, electron emitting device, charging device, image forming apparatus, electron-beam curing device, light emitting device, image display device, air blowing device, and cooling device

A method for producing an electron emitting element that includes:

• an electrode substrate;
• a thin-film electrode facing the electrode substrate;
• and
• an electron acceleration layer sandwiched between the electrode substrate and the thin-film electrode,
• as a result of a voltage applied between the electrode substrate and the thin-film electrode, electrons being accelerated in the electron acceleration layer so as to be emitted from the thin-film electrode,
• the method comprising the steps of:
• forming the electrode acceleration layer by applying, on the electrode substrate, a dispersion solution in which insulating fine particles, conductive fine particles and a crystalline electron transport agent are dispersed;
• forming the thin-film electrode on the electron acceleration layer;
• and
• crystallizing the crystalline electron transport agent.
