    Abstract: A toner quantity measuring apparatus in which an input offset voltage is applied to the output side of an irradiation quantity monitoring light receiving element, so that a light emitting element remains turned off unless a light quantity control signal exceeds a predetermined signal level. Prior to irradiation of light upon an intermediate transfer belt and measurement of a toner quantity, a light quantity control signal below the predetermined signal level is supplied to an irradiation quantity adjusting unit and the light emitting element is turned off without fail. A memory stores, as a dark output voltage, an output voltage from a reflection quantity detecting unit upon the turning off. Light reflected from the intermediate transfer belt is split into p-polarized and s-polarized light to detect a toner quantity and colors of the toner. In actual measurement of the toner quantity, with light irradiated upon the intermediate transfer belt, the dark output voltage is subtracted from the output voltage outputted from the reflection quantity detecting unit, whereby an influence of the dark output voltage is eliminated.

    Abstract translation: 一种调色剂量测量装置，其中输入偏移电压施加到照射量监视光接收元件的输出侧，使得除非光量控制信号超过预定信号电平，否则发光元件保持关闭。 在将光照射到中间转印带上并测量调色剂量之前，将低于预定信号电平的光量控制信号提供给照射量调节单元，并且发光元件关闭。 作为暗输出电压，存储器在关闭时存储来自反射量检测单元的输出电压。 从中间转印带反射的光被分裂为p偏振和s偏振光，以检测调色剂的调色剂量和颜色。 在调色剂量的实际测量中，通过照射到中间转印带上的光，从反射量检测单元输出的输出电压中减去暗输出电压，从而消除暗输出电压的影响。

    Abstract: In an apparatus, first and second processing modes are prepared to determine an optimal development bias. Either one of the first processing mode and the second processing mode is selected as a processing mode in accordance with an operation status of the apparatus. Hence, it is possible to select and execute the most appropriate processing mode in accordance with an operation status to thereby efficiently and highly accurately determine an optimal value of a development bias which is one density controlling factor.

    Abstract: Power transmission members (91), which transmit rotational drive force from a drive source (81), such as a motor, to an intermediate transfer drum (41D) is elastically deformed due to a load change which is generated as a cleaning part (49) contacts and moves away from the intermediate transfer drum (41D). Registration control amounts (Ra, Rb and Rc) attributed to the elastic deformation are obtained in advance. Transfer start positions for toner images in at least one or more toner colors out of four toner colors are corrected based on the registration control amounts (Ra, Rb and Rc), whereby registration deviations are suppressed to minimum and a high-quality color image is obtained.
