Abstract
An exposure apparatus performs exposure of a photosensitive body by an array of light emitting devices to form an image as a latent image thereon. The array of light emitting devices incorporate micro-optical cavities. The micro-optical cavities limit wavelengths of light emitted from the array of light emitting devices, so that the wavelength at a peak of emitted light is in a half width region of sensitivity versus wavelength of the photosensitive body.
