Abstract
The invention provides an image forming apparatus in which orbit shift can be prevented to perform good image display in an electron beam emitted from the electron-emitting device adjacent to the spacer when an antistatic spacer coated with a high resistance film is used. A surface shape is controlled by forming a fine particle film on the surface of a row directional wiringin which a spaceris arranged, the electron emission is realized from electron-emitting areasandnear contacting areasandin a non-contacting areain which the spaceris not in contact with the row directional wiringand the non-contacting areaof the spaceris irradiated with the electron to decrease a potential, which allows a good equipotential lineto be formed.
