ABSTRACT:
In an image forming apparatus, a support member (50) for maintaining the distance between a face plate (30) and a rear plate (31) is interposed between the face plate (30) and the rear plate (31). An intermediate layer (52) is formed at apportion near the face plate (30). The intermediate layer (52) is a low-resistance film, and is set to have almost the same potential as that of the face plate (30). As a result, an electron beam from an electron-emitting portion near the support member (50) follows an orbit which steadily comes close to the support member near the face plate. By setting the interval between electron-emitting devices adjacent to each other via the support member to be larger than the interval between devices adjacent to each other without the mediacy of the support member, the electron beam is irradiated on a proper position on the face plate (30).
