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。

摘要： A process control apparatus of electrophotographic apparatus has an optical sensor for optically detecting the density of toner patches formed on a photoreceptor drum. The present apparatus is further provided with a control device for controlling lamps for the copying process, chargers and other elements. A toner patch is formed on the photoreceptor so as to be located between every two toner images for a copying operation. The control device controls the lamps, chargers and other elements in accordance with the result of the toner patches detected by the optical sensor so as to stabilize the copying picture quality. With the arrangement, it is avoided that the job efficiency during the copying operation deteriorates, and the control data obtained from the toner patches is soon used for the toner image formation for the copying operation, thereby ensuring that the process control improves in accuracy.

摘要： In an optical discharge apparatus used in an electrographic image forming apparatus, by forming, on a light guiding member, a diffusing reflecting face for reflecting light from an LED lamp towards a photosensitive drum, and by supplementing the amount of light by altering the height of the diffusing reflecting face to the light emitting face and the width of the diffusing reflecting face in accordance with their distance from the light source, the light intensity distribution of the irradiating light that is irradiated onto the photosensitive drum is made uniform. Furthermore, since light that leaks from the diffusing reflecting face is reflected by a reflecting film that is pasted onto an upper face in the vicinity of a rear end portion of the light guiding member, and returned to the interior of the light guiding member, the amount of light that is irradiated from the light emitting face in the vicinity of the rear end portion of the light guiding member increases, and thus it is possible to further increase the uniformity of the light intensity distribution of the irradiating light. Furthermore, an optical discharge apparatus used in an electrographic image forming apparatus is provided with a light guiding member that is arranged facing the photosensitive drum of the image forming apparatus, and an LED lamp for irradiating the light onto the light incident face of the light guiding member. A diffusing reflecting face for reflecting the light from the LED lamp toward the photosensitive drum is formed on the light guiding member. The rear end face of the light guiding member is an optically transparent face, and the amount of irradiating light that is irradiated onto the photosensitive drum from the vicinity of the rear end portion of the light guiding member increases by forming a reflecting face behind the rear end face of the light guiding member.
