Abstract:
A method for manufacturing an image forming apparatus having a multiple electron source in which a plurality of emitters are disposed on a substrate and fluorescent materials for emitting light by irradiation of electron beam from the multiple electron source, comprising:a first measurement step of measuring change of luminance, when a pulse having a plurality of amplitude larger than drive voltage is applied to the predetermined number of the emitters, with respect to the amplitude of the pulse and the number of the pulse; a step of preparing, on the basis of the measurement result of the first measurement step, a look-up table for storing the amplitude of the pulse and the number of the pulse for shifting characteristic of emitters to a predetermined luminance target value; a second measurement step of measuring the luminance when the drive voltage is applied to the emitter; and a step of applying, on the basis of the measurement result of the second measurement step, characteristic shift voltage comprising a plurality of pulses in which the amplitude of the pulse obtained from the look-up table has two or more values, to the emitter.
