Electron beam-generating apparatus, image-forming apparatus, and driving methods thereof

摘要

A driving method for an electron beam-generating apparatus having an electron source having a plurality of electron-emitting devices, and a plurality of modulation means for modulating electron beams emitted from the electron source in correspondence with information signals comprises applying a cut-off voltage to a first modulation means adjacent to a second modulation means to which an ON voltage is applied as the information signals in modulation of the electron beam.
