ABSTRACT:
An image-forming apparatus of the present invention includes: a vacuum container constituted by disposing in opposition to each other a rear plate with an electron source formed thereon, and a face plate having an image display region provided with at least phosphors for being irradiated with electrons emitted from the electron source to form an image and anodes disposed on the phosphors; anode potential supplying means for supplying an electric potential higher than that of the electron source to the anode; at least one electroconductive member provided at a site outside of the image display region on an inner surface of the face plate; potential supplying means for supplying to the electroconductive member an electric potential at a level between a lowest electric potential of those which are applied to the electron source and an electric potential applied to the anode; first and second resistant members electrically connected between the anode and the electroconductive members, having resistances higher than that of the anode and having different resistances from each other, wherein the anode, the first resistant member, the second resistant member, and the electroconductive member are electrically connected in series.
