An image forming apparatus in which a first substrate (1) provided with an electron-emitting device (7) and an image displaying member (2) which electrons emitted from the electron-emitting device irradiate are arranged to be opposed is provided with a deflecting means (31-33,42) deflecting the electrons emitted from the electron-emitting device and a trapping unit (31,42) trapping an inert gas ionized by the electrons. Thereby, the damages of the electron-emitting device by the inert gas are prevented, and the life of an image display apparatus is aimed to be elongated.
