    Abstract: This invention relates to an electron source and an image forming apparatus each of which particularly comprises a surface conduction type electron emitting element as an electron emitting element, a method of manufacturing an electron source and an image forming apparatus, in which the energization forming treatment step of the surface conduction type electron emitting element is performed by applying a voltage to an electron emitting portion formation thin film via a nonlinear element connected in series with the thin film and having nonlinear voltage/current characteristics, an electron source and an image forming apparatus in each of which the nonlinear element is connected in series with the surface conduction type electron emitting element, and a method of driving the same. Typical nonlinear elements include rectification and diode elements. In addition an element for removing a noise component superposed on the input signal is connected in series with surface conduction type electron emitting element.

    Abstract: An electron source emits electrons as a function of input signals. The electron source comprises a substrate (1), a matrix of wires having m row wires and n column wires laid on the substrate with an insulator layer interposed therebetween, and a plurality of surface-conduction electron-emitting devices each having a pair of electrodes (5,6) and a thin film (4) including an electron emitting region (3) and arranged between the electrodes. The electron-emitting devices are so arranged as to form a matrix with the electrodes connected to the respective row and column wires. Each pixel unit is irradiated by at least two electron beams emitted from the respective electron emitting regions which are juxtaposed with interleaving the higher potential device electrode therebetween and a gap interval W in the juxtaposing direction of which satisfies equation (1) below: K2 x 2H(Vf/Va) ≥ W/2 ≥ K3 x 2H(Vf/Va) where K2 = 1.25 +/- 5.05, K3 = 0.35 +/- 0.05, H is the distance between the surface-conduction electron-emitting devices and the image-forming member, Vf is the voltage applied to the surface-conduction electron-emitting device and Va is the voltage applied to the image-forming member.
