A vacuum fluorescent display includes a front glass member, substrate, phosphor film, an electron-emitting portion, electron extracting electrode, and insulating support member. The front glass member has light transmission properties at least partly. The substrate opposes the front glass member through a vacuum space. The phosphor film is formed on that surface of the front glass member which opposes the substrate and has a predetermined display pattern. The electron-emitting portion is mounted on the substrate to oppose the phosphor film, and has an electron-emitting surface corresponding to the display pattern. The electron extracting electrode is arranged in the vacuum space between the electron-emitting portion and the phosphor film to be spaced apart from the electron-emitting portion by a predetermined distance. The insulating support member is formed on the substrate and adapted to support the electron extracting electrode and divide the electron-emitting surface of the electron-emitting portion into a plurality of regions.

Method and apparatus for manufacturing a heater roller which includes a cylindrical electrically insulating substrate having an outer circumferential surface, and an electrically resistive heat generating layer formed on the substrate for heating a desired member in evenly pressing contact with that member, wherein an electrically resistive paste for forming the electrically resistive layer is delivered from a paste delivery tube of a paste delivery device onto the outer circumferential surface of the substrate, while the cylindrical substrate is rotated about its axis and while the paste delivery device and the electrically insulating substrate are fed relative to each other in the axial direction of the cylindrical substrate, such that the relative feeding speed is controlled in relation to the relative position of the paste delivery device and the substrate in the axial direction of the substrate, within a range that permits formation of a film of the electrically resistive paste on the substrate, which film is continuous in the axial direction of the substrate.
