Color image forming apparatus having image intensifier unit

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:

• thermoelectron emitting means for emitting thermoelectrons as a primary electron signal representing the image information;
• secondary electron emitting/multiplying means for converting the primary electron signal into secondary electrons and multiplying the secondary electrons;
• and
• fluorescent light emitting means for converting the multiplied secondary electrons into fluorescent light having a wavelength in the photosensitive wavelength range of the photosensitive recording medium and irradiating the fluorescent light onto the photosensitive recording medium, thereby forming an image on the photosensitive recording medium.

An image forming apparatus for irradiating a color image light on a photosensitive recording medium having plural photosensitive wavelength ranges on the basis of a color image information to thereby form a color image on the photosensitive recording medium, comprising:

• primary electron emitting means for emitting a primary electron signal spacedly encoded according to a plurality of colors of the color image information, the primary electron emitting means being responsive to corresponding spacedly dispersed incident light of at least one first wavelength;
• secondary electron emitting/multiplying means for converting the primary electron signal in to secondary electrons and multiplying the secondary electrons;
• and
• fluorescent light emitting means for converting the multiplied secondary electrons into red, green and blue color image lights having second wavelengths matching with the photosensitive wavelength ranges of the photosensitive recording medium and irradiating the color image lights onto the photosensitive recording medium, thereby forming a color image on the photosensitive recording medium.
