    • An image forming apparatus including an image carrier; an intermediate transfer member having a first portion and a second portion that has a higher glossiness than that of the first portion; a primary transfer member; a light source to emit light to the intermediate transfer member side; a detector to detect intensity of reflected light emitted from the light source and then reflected from the intermediate transfer member and a density adjustment pattern formed on the intermediate transfer member; a processor including a light-emission intensity adjuster to adjust light-emission intensity from the light source based on detected intensity of light reflected from the second portion of the intermediate transfer member; and an image forming condition controller to control image forming conditions for forming a toner image based on the detected intensity of the light reflected from the density adjustment pattern formed on the intermediate transfer member.
    • 一种图像形成装置,包括图像载体; 具有第一部分和第二部分的中间转印部件具有比第一部分光泽度更高的光泽度; 一次转让成员; 向中间转印部件侧发光的光源; 检测器,用于检测从光源发射的反射光的强度,然后从中间转印部件反射,并形成在中间转印部件上的浓度调节图案; 处理器,其包括发光强度调节器,用于基于从所述中间转印构件的第二部分反射的检测到的光的强度来调节来自所述光源的发光强度; 以及图像形成条件控制器,用于基于从形成在中间转印部件上的浓度调节图案反射的光的检测强度来控制形成调色剂图像的图像形成条件。
