Abstract:
An image recording device for recording an image on a recording medium by main scanning and subscanning a light beam with respect to the recording medium by relatively moving the light beam and the recording medium, comprising:a light source which emits a laser beam which has been modulated in accordance with image data; an optical fiber having an innermost core, a clad covering the core, a light exit portion, and a light entry portion optically joined to the light source, which receives the laser beam into the optical fiber, the core having a cross-sectional configuration in a plane substantially orthogonal to an optical axis direction of the laser beam corresponding to at least one of an elongated configuration and a configuration having two parallel sides at least at the light exit portion of said optical fiber; and a focusing lens which focuses, on the recording medium, a light beam emitted from the light exit portion of said optical fiber.
