摘要： An image forming apparatus is provided which is capable of forming higher-quality images by detecting a toner concentration with higher accuracy to attain appropriate toner supply and image density. A value obtained by adding a correction value based on a temperature, humidity, a print coverage, or the like to a developer concentration adjustment value is set as a control voltage value Vc which is to be inputted to a toner concentration sensor, and an output value of the toner concentration sensor is detected for each of process speeds. A difference between the output value detected and a value at reference process speed is calculated and based on the difference, a correction value is further calculated. Such another calculation of the correction value with use of the output value detected allows for highly accurate correction.

摘要： An apparatus includes a system controller which calculates a ratio of a first signal to a second signal and adjusts a control parameter of an electrophotographic reproduction process so that the density of fog indicated by the ratio is within a predetermined range. A first optical sensor outputs the first signal by detecting a reflectance of a non-image area on the photoreceptor between a developing unit and a transfer charger. A second optical sensor outputs the second signal by detecting a reflectance of a surface of the photoreceptor between a cleaning unit and a charger. The system controller controls developer including toner and carrier to be agitated when the ratio obtained after adjusting the control parameter is still outside the predetermined range. Since the density of fog is detected with accuracy by calculating the ratio, copy quality is stabilized even when temperature changes. Moreover, even if the ratio is outside the predetermined range as a result of the supply of toner which has deteriorated due to a heat history, the deterioration of toner is restored by agitating the developer. It is thus possible to prevent copy quality from being degraded.
摘要翻译： 一种装置包括：系统控制器，其计算第一信号与第二信号的比率，并调整电子照相再现处理的控制参数，使得由比率指示的雾度浓度在预定范围内。 第一光学传感器通过检测显影单元和转印充电器之间的感光体上的非图像区域的反射率来输出第一信号。 第二光学传感器通过检测清洁单元和充电器之间的感光体的表面的反射率来输出第二信号。 当调整控制参数后获得的比例仍然在预定范围之外时，系统控制器控制显影剂，包括调色剂和载体被搅拌。 由于通过计算比例来精确地检测雾的浓度，即使温度变化，复印质量也被稳定。 此外，由于由于热历史而劣化的调色剂的供给，即使该比例在预定范围之外，也可以通过搅拌显影剂来恢复调色剂的劣化。 因此，可以防止复制品质恶化。
