MANUFACTURE OF ELECTRON SOURCE AND IMAGE FORMING DEVICE, AND MANUFACTURE DEVICE THEREOF

摘要

PROBLEM TO BE SOLVED: To suppress an occurrence of abnormal voltage in a current carrying process. SOLUTION: A manufacturing method for an electron source 101 that has an electron-emitting element with a pair of conductive members and a first and second wirings each connected to each of the pair of conductive members, comprises a voltage applying process to apply a pulsed voltage to the pair of conductive members. The pulsed voltage is limited to exclude a particular frequency band contained in a pulsed voltage outputted from a pulse power supply.
