ABSTRACT:
With the present invention, there is provided a driving method that favorably drives an electron source, which is driven in a passive matrix manner, without being affected by a disturbance. There is also provided an image-forming apparatus that uses this electron source. An anode electrode having a constant potential is arranged over a plurality of electron-emitting devices including gate electrodes and cathode electrodes. During passive matrix driving of the electron source where the amount of electrons to be emitted is adjusted by modulating potentials between the cathode electrodes and the gate electrodes, a predetermined time difference is maintained between the driving of signal lines in a group and the driving of signal lines in another group during the driving of signal lines divided into N groups after selection of scanning lines. If a scanning line capacity is referred to as C and a scanning line resistance is referred to as R, this time difference is set so as to be equal to or more than CR (approximately equal to CR).
