There are provided a method of properly driving an electron source, in matrix driving in which each signal line and scanning line have large capacitance and are capacitively coupled to disturb each other, without any influence of the disturbance, an electron source using the driving method, an image-forming apparatus, and a method of driving the image-forming apparatus. In an electron source made up of electron-emitting devices each having a gate electrode and cathode electrode, in performing passive matrix driving operation of driving a plurality of signal lines together after selecting a scanning, letting V1off be the OFF voltage of the scanning line and V2On be the ON voltage of a signal line, V1off>V2On. In addition, V1off-V2On, is set to be large enough to prevent a gate/cathode voltage from changing to the ON region during an OFF period even if the voltage changes due a disturbance caused by driving. Letting V1On be the ON voltage of a scanning line and V2off be the OFF voltage of a signal line, V1On>V2off and V1off-V2On>V1On-V2off.
