<p>PROBLEM TO BE SOLVED: To provide an image forming device that can prevent luminance dispersion and comprises a plurality of electron emission elements within a relatively short manufacturing time. SOLUTION: A plurality of dummy electron emission elements which do not contribute to image formation is previously formed in an electron source substrate 71 and wired with an X-direction airing 76, the activation of the dummy electron emission elements is performed at least at an initial period of starting an activation process, and thereafter, and the activation of electron emission elements 74 which are connected to X-direction wiring 72 and contribute to image formation is carried out.</p> |
