ABSTRACT:
An image forming apparatus for irradiating an image light on a photosensitive recording medium having at least one photosensitive wavelength range on the basis of an image information to thereby form an image on the photosensitive recording medium, comprising a semiconductor laser for emitting an image light or a thermal cathode for emitting thermoelectrons having the image information, a photomultiplier or microchannel plate for converting the image light or the thermoelectrons into secondary electrons while the image forming information is kept, and multiplying the secondary electrons, and a fluorescent screen for converting the multiplied secondary electrons into an intensified image light. The intensified image light may be supplied on a photosensitive recording medium while the image forming information is kept, thereby forming an image on the photosensitive recording medium.
