Zusammenfassung:	To solve the problem in which: management of glossiness of a product is important for electrophotography; however, an image forming apparatus generally uses a component dedicated to detect glossiness, and the component is not used for purposes other than glossiness detection, and thereby a cost for a result is increased.SOLUTION: An image reading device having a line sensor reading diffused and reflected light mounted thereon and a black image uniformly generated by an image forming apparatus to enable detection of a difference in glossiness in the same plane at a low cost without using a component dedicated to glossiness detection.SELECTED DRAWING: Figure 1 【課題】電子写真にとって成果物の光沢度管理は重要であるが、一般的に光沢度を検知するために専用の部品を用いており、光沢度の検知以外に用途が無いため成果に対してかかるコストが大きくなってしまう。【解決手段】拡散反射光を読み取るラインセンサを搭載した画像読取装置と、画像形成装置によって生成された一様な黒色画像を用いることで、光沢度検知専用部品を用いることなく低コストで同一面内の光沢度差の検出を可能にする。【選択図】図１
