摘要： An image forming apparatus transfers a toner image from a photoconductive image carrier to a recording medium with a transfer roller and senses the density of a particular toner pattern formed on the image carrier with an optical sensor. A voltage of a first polarity opposite the polarity of the toner is applied to the transfer roller when the toner image is to be transferred to the recording medium. A voltage of a second polarity identical to the polarity of the toner is applied to the transfer roller when the toner pattern is to be moved between the image carrier and the transfer roller. Thus, even when a toner pattern is brought to the transfer roller, the transfer roller is not released from the photoconductive element.
摘要翻译：图像形成装置将调色剂图像从感光图像载体转印到具有转印辊的记录介质上，并用光学传感器感测形成在图像载体上的特定调色剂图案的浓度。当将调色剂图像转印到记录介质时，与转印辊的极性相反的第一极性的电压施加到转印辊上。当调色剂图案在图像载体和转印辊之间移动时，与转印辊的极性相同的第二极性的电压被施加到转印辊上。因此，即使将调色剂图案带到转印辊上，转印辊也不会从光电导元件释放。

摘要： A control system for an image forming device includes a sensor mounted on an optical path unobstructed by elements that are subject to wear for detecting a time varying signal representing reflected light from both a photoconductive element and a transfer sheet internal to the image forming device, a memory storing reference values, and a controller to control an image forming operation based on the reference values stored in the memory and the time-varying signal received from the sensor. The controller reads the time-varying signal from the sensor and compares the time-varying signal read to the reference values to determine a condition of the image forming device.
