摘要： A copying machine wherein a developing device is provided with a first sensor for detecting the toner density in a developer and a second sensor which is provided around a photosensitive drum for detecting the amount of deposited toner on a test pattern. The toner supply is controlled according to a result detected by the second sensor. When the toner density is judged high from a result detected by the first sensor, a developing bias voltage is set high by a computer, and when the toner density is judged low, the developing bias voltage is set low.

摘要： An image forming apparatus, such as an electrophotographic copier, forms a test image on a photosensitive member, under constant image forming conditions, and the amount of toner adhering to the photosensitive member is detected. The detected amount of toner is converted into a developer toner concentration, based on a conversion standard. The toner concentration is used to control the operation of a toner replenishment device. The conversion standard is periodically corrected by forming a test image using a developer having a known toner concentration, detecting the amount of adhered toner, comparing the detected result to a standard value, and selecting one conversion standard table from among a number of different conversion tables.

摘要： The image forming apparatus is provided with a detecting means for detecting transfer efficiency when transferring a toner image from a photosensitive member to a transfer sheet, and a developing efficiency changing means for changing developing efficiency based on the transfer efficiency detected by the detecting means, and corrects the toner consumption predicted by the predicting means based on the transfer efficiency as detected by the detecting means, so as to determine the amount of toner to be replenished. When the developing efficiency is changed based on the transfer efficiency, toner consumption also changes, and does not match the predicted toner consumption. According to the present invention, toner concentration in a developer can be even more accurately controlled by correcting the predicted toner consumption by the change in transfer efficiency. Detection of transfer efficiency is achieved by a method of indirectly detecting humidity in the apparatus, or a method of measuring the amount of toner transferred to a transfer member.
摘要翻译：图像形成装置设置有用于在将调色剂图像从感光构件转印到转印纸上时检测转印效率的检测装置，以及用于基于由检测装置检测的转印效率来改变显影效率的显影效率改变装置，以及基于由检测装置检测的转印效率来校正由预测装置预测的调色剂消耗量，以便确定要补充的调色剂的量。当基于转印效率改变显影效率时，调色剂消耗也改变，并且与预测的调色剂消耗不匹配。根据本发明，通过根据转印效率的变化校正预测的调色剂消耗，可以更加准确地控制显影剂中的调色剂浓度。通过间接检测设备中的湿度的方法或测量转印到转印部件的调色剂量的方法来实现转印效率的检测。

摘要： Techniques for unsupervised management of a question and answer (QA) forum include labeling of answers for quality purposes, and identification of experts. In a QA thread, a ranking of answers may include an initial labeling of the longest answer in each thread as the best answer. Such a labeling provides an initial point of reference. Then, in an iterative manner answerers are ranked using the labeling. The ranking of answerers allows selection of experts and poor or inexpert answerers. A label update is performed using the experts (and perhaps inexpert answerers) as input. The label update may be used to train a model, which may describe quality of answers in one or more QA threads and an indication of expert and inexpert answerers. The iterative process may be ended upon convergence or upon a maximum number of iterations.
