摘要： An image forming apparatus includes image forming sections for respective colors, the image forming sections facing an outer surface of an intermediate transfer belt on an outward path. A transfer roller is provided on a returning path and is movable to a contact position where the transfer roller is pressed against the intermediate transfer belt or to a detachment position where the transfer roller is detached from the intermediate transfer belt. A density sensor is provided for detecting a density of toner image on the intermediate transfer belt. In an image quality adjustment operation, image forming sections form a toner image row on the intermediate transfer belt, and the density sensor measures densities. A length of the toner image row is smaller than a length of the intermediate transfer belt between the endmost photoreceptor drum on the downstream side and the transfer roller.

摘要： A fiber-producing apparatus includes a storage tank for storing a melt of a source material, an electric storage tank heater, a non-contact thermometer for the melt, a temperature control section which between the electric heater and its power supply, which controls the electric heater based on measurement results obtained from the non-contact thermometer to adjust the temperature of the melt, a nozzle for ejecting the melt in the storage tank, a collector for collecting a fiber, a voltage generator for electrifying the melt, and an insulating transformer disposed between the temperature control section and the electric heater. Since a closed circuit is formed by the electric heater, the electric heater power supply, the temperature control section, and the insulating transformer disposed therebetween, no high-voltage current flows into the electric heater power supply or the temperature control section. This allows stable spinning to be readily performed without breaking the apparatus.

摘要： A high density detecting toner pattern is formed on a photosensitive body and a high density correction is effected by comparing a value detected by a reflection sensor with a high density reference value so as to maintain an image density at a specific level. An image density correcting section adopts a result of the preceding high density correction as the high density reference value, and compares the same with a result of a current high density correction. The image density correcting section effects the half-tone density correction only when a difference reaches or exceeds a preset difference reference value by forming a half-tone density detecting toner pattern on the photosensitive body and comparing a value detected by the reflection sensor with a half-tone reference value. Consequently, it has become possible to provide an image forming apparatus which can maintain a density output of an entire image at a specific level for any kind of images including solid, line, and half-tone, etc. while shortening a time required for the density correction and reducing a quantity of toner consumed for the density correction.
摘要翻译：在感光体上形成高密度检测调色剂图案，并且通过将由反射传感器检测的值与高密度参考值进行比较来实现高密度校正，以将图像浓度保持在特定水平。图像浓度校正部分采用先前的高浓度校正的结果作为高密度参考值，并将其与当前高密度校正的结果进行比较。图像浓度校正部仅通过在感光体上形成半色调浓度检测调色剂图案而将差分达到或超过预设差值基准值来实现半色调浓度校正，并将反射传感器检测到的值与半参考值。因此，可以提供一种图像形成装置，其可以将包括实线，线条和半色调等的任何种类的图像的整个图像的浓度输出保持在特定的水平，同时缩短所需的时间密度校正和减少密度校正所消耗的调色剂量。

摘要： A test patch image is formed and the density thereof is detected to maintain the image quality at a constant level. One of the image forming conditions, for example, the developing bias voltage of the developing unit inside the image forming apparatus that serves as a density controller, and is controlled in accordance with the detection result. Here, a humidity sensor for detecting the environmental change, that is, the humidity, is provided inside the apparatus, and the reference value of the toner mixing ratio is changed and corrected while the developing unit is operating when the humidity sensor detects a change in humidity. However, the toner mixing ratio is maintained and neither changed nor corrected when the density of the test patch image remains at the same level, so that the developing bias voltage is not corrected. Consequently, the correction of the toner mixing ratio is neither changed nor corrected in response to the change in humidity alone, thereby making it possible to maintain a stable image quality state.

摘要： The static latent image formed on the photoreceptor which has been charged, by exposing it to light, is developed through four colors of developing units, i.e., yellow, magenta, cyan and black, forming toner images on the photoreceptor. These toner images are transferred to the transfer drum. Before forming the toner images, a device is provided to correct the measurement value of toner density obtained using the light emitter and photosensor into an exact value. Based on the reflected light from a white-coated area formed on the transfer drum, two levels of the intensities of emitted light are determined. The intensity of received light is compared to the standard value so that the output value from the photosensor corresponding to the toner density is made to approximate the standard value.
