Abstract
An image forming apparatus such as an image display apparatus has spacers the charging of the surface of which can be reduced as well as the occurrence of discharge. The image forming apparatus includes an envelope, an electron source disposed within the envelope, an image forming member for forming an image by irradiation with electrons emitting by the electron source, and a spacer disposed between electrodes to which mutually different voltages are applied within the envelope. The spacer has conductivity and is electrically connected to the electrodes via conductive layers, and each of the conductive layers has an end portion defining a shape which is a combination of a linear portion and a curved portion or a combination of a linear portion and an obtuse-angle portion.
