    • An image forming apparatus includes an image information acquisition unit that acquires image information; a toner image formation unit that forms, in response to a control parameter, a toner image on a surface of an image carrier based on the image information; an image density detection unit that produces a detection result indicative of image density of the toner image; and a control unit that determines whether to use a predetermined region in the toner image formed on the surface of the image carrier based on the image information for a detection of the image density of the toner image, and when the predetermined region is determined to be used for the detection of the image density, corrects the control parameter used by the toner image formation unit based on the detection result so as to maintain the image density in the predetermined region within a predetermined range.
    • 图像形成装置包括获取图像信息的图像信息获取单元; 调色剂图像形成单元,其响应于控制参数,基于所述图像信息形成图像载体的表面上的调色剂图像; 图像浓度检测单元,其产生指示调色剂图像的图像浓度的检测结果; 以及控制单元,其基于用于检测调色剂图像的图像浓度的图像信息来确定是否使用形成在图像载体的表面上的调色剂图像中的预定区域,并且当确定预定区域为 用于检测图像浓度,基于检测结果校正由调色剂图像形成单元使用的控制参数,以将预定区域中的图像浓度保持在预定范围内。
