    • A toner density detection apparatus has a sensor unit and a controller. The sensor unit irradiates a toner patch formed on an image carrier with light, splits the light reflected by the toner patch into first and second light components, receives the first and second light components, and outputs first and second light reception signals. The controller causes an analog/digital converter to convert, based on a reference voltage, the output first and second light reception signals into first and second digital data, and detects the density of the toner patch based on the first and second digital data. The toner density detection apparatus adjusts the toner density detection value based on a comparison between a first reference value stored in advance and the first digital data, and a comparison between a second reference value stored in advance and the second digital data.
    • 调色剂浓度检测装置具有传感器单元和控制器。 传感器单元用光照射形成在图像载体上的调色剂片,将由调色剂片反射的光分解成第一和第二光分量,接收第一和第二光分量,并输出第一和第二光接收信号。 控制器使得模拟/数字转换器基于参考电压将输出的第一和第二光接收信号转换成第一和第二数字数据,并且基于第一和第二数字数据检测调色剂贴片的密度。 调色剂浓度检测装置基于预先存储的第一参考值与第一数字数据之间的比较以及预先存储的第二参考值与第二数字数据之间的比较来调节调色剂浓度检测值。
