Abstract
In a method for producing an electron source substrate having a matrix of electron emitting elements formed by dispensing droplets of a solution containing a material for conductive thin film between each pair of element electrodes arranged in a matrix pattern on substrate, by use of an ink jet device, the ink jet device is the one having plural nozzles, delivery amounts of the respective nozzles are detected, the delivery amounts of the respective nozzles are adjusted based on the detection results, and thereafter dispensing of the droplets is carried out, during the dispensing of droplets, the substrate is moved relative to the ink jet device, and the droplets are dispensed from the plural nozzles to areas between each pair of element electrodes in plural rows or columns simultaneously and in parallel. An image forming apparatus is produced by placing at least a face plate equipped with fluorescent substance opposite the electron source substrate produced by the above method.
