の自動画像調整装置。[Scope of Claim for Utility Model Registration] (1) A copying machine that can form a copy image at a predetermined magnification corresponding to the original, and that automatically adjusts the image forming conditions to adjust the density of the magnified image according to the original. The automatic image adjustment device includes a reference member having a reference density, a light source that illuminates the reference member and the original, a detection member that detects reflected light from the reference member and the original, and a detection member that detects reflected light from the reference member. An automatic image adjustment device for a copying machine, comprising: a document density detecting means having a means for calculating a ratio of information of reflected light from the document, and adjusting the image forming conditions according to the output of the document density detecting means. (2) The scope of the utility model registration claim that the light reflected from the document is reflected light for each predetermined width of the document, and the image forming conditions are determined for each area image of the developing device corresponding to the predetermined width of the document. The automatic image adjustment device for a copying machine according to item 1.
