Beam recording apparatus with intensity control
 An image recording apparatus records an image on a recording medium by scanning a spot light beam in accordance with image information. The apparatus has a storage device for storing the image information corresponding in amount to at least three sub-scan lines, and a light intensity controller for increasing and decreasing the intensity the light beam in accordance with the contents of the storage device relative to a standard intensity. A light beam of the standard intensity satisfies a relation of 1.8.ltoreq.d/p where d represents a light beam diameter (defined as the diameter at which the light beam intensity lowers to 1/e.sup.2 (e: base of the natural logarithms) of the intensity at the light beam center, and p represents an interval between respective scan lines.
