CHARACTERISTICS ADJUSTING METHOD OF ELECTRON SOURCE AND IMAGE FORMING DEVICE, ELECTRON SOURCE AND IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a characteristics adjusting method of an electron source and an image forming device which does not easily have an error (have high precision) to the target value and an electron source and an image forming device. SOLUTION: As shown in the figure (b), the voltage value Va that is impressed on the anode electrode from the power source during the adjustment of the characteristics is made smaller than that when the drive voltage Vdrv is impressed from the power source (second period).
