Abstract:
An image-forming apparatus comprising:an electron beam source composed of a plurality of electron-emitting devices, each of said electron-emitting devices having a pair of electrodes to which a voltage is applied and an electron-emitting region disposed between said pair of electrodes, said pair of electrodes and said electron-emitting region being arranged side-by-side;image-forming members for forming an image upon irradiation by respective electron beams emitted from said electronic-emitting devices;drive means for applying respective drive signals to between said pair of electrodes of said electron-emitting devices in accordance with image signals;voltage applying means for applying a voltage to between said electron-emitting devices and said image-forming members; andvoltage adjustment means adapted to adjust the voltage applied to between said electron-emitting devices and said image-forming members by said voltage applying means to correct the trajectories of the respective electron beams in accordance with a positional deviation of an as-assembled relative position between said electron-emitting devices and said image-forming members from a predetermined desired relative position between said electron-emitting devices and said image-forming members.
