Comfortable sensation of living bodies is estimated, considering individual differences in biological information on the living bodies staying or residing in a common space, and stimulation contents is properly controlled. A stimulation generator 300 generates a stimulation to be applied to users. Biological information acquirers 101a and 101b acquire time-series data of biological information on the users. Parameter extractors 102a and 102b extract a parameter which is changed with a lapse of time by analyzing the time-series data. Thermal sensation estimators 103a and 103b estimate statuses of the users to the stimulation generated by the stimulation generator 300, based on the parameter extracted by the parameter extractors 102a and 102b. A multi-user thermal sensation processor 105 integrates estimation results on the users estimated by the thermal sensation estimators 103a and 103b into a single estimation result. A stimulation controller 104 controls the stimulation generator 300 based on the integrated estimation result.

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.

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:
Developing devices are provided adjacent to a light sensitive element. An intermediate transfer drum is provided adjacent to the light sensitive elements. After exposure of the light sensitive element, a first color or third color image is formed on the light sensitive element. On the other hand, after exposure of the light sensitive element, a second color or fourth color image can be formed on the light sensitive element. The first color image is transferred from the transfer unit to the intermediate transfer drum at the first transfer portion, and the second color image is transferred from the transfer unit at the second transfer portion so as to be superimposed on the first color image. Similarly, the third color image is transferred so as to be superimposed on the second image and the fourth color image is transferred so as to be superimposed on the third color image to the intermediate transfer drum. Accordingly, the first to fourth color images are superimposed. Thereby, downsizing of the device and cost reduction are achieved and image formation speed is facilitated.
