摘要： Images based on each of a plurality of color components are formed; the formed images are transferred on each transfer medium to form an image quality determining image; the image quality of the image quality determining image is determined on the basis of the detected density thereof, an adjustment image is formed by overlaying and transferring an image of other color component to be adjusted to the reference image of the reference color image out of the plurality of color components, on the transfer medium; the density of the adjustment image is detected; and the image forming position of the other color component to be adjusted is adjusted on the basis of the detected density. At the time of executing the color matching adjustment process for detecting the overlaid state of color component images, it is determined whether a specified time has passed or not since the previous adjustment process, a specified number of images are formed or not, environments are changed or not, and the power source is turned on or off or not. When it is predicted that the quality of the formed image is out of an appropriate range, a quality checking image is formed, its image quality is checked, and the color matching adjustment process is executed only when it is within an appropriate range.

摘要： In an optical scanning device for forming an electrostatic latent image on an image-bearing body with scanning beam released from a light source, a support body having a plurality of supporting faces and first and second optical means for directing the scanning beam from the light source onto the image-bearing body are installed. Moreover, in the support body, a light transmitting means for transmitting the scanning beam from the first optical means to the second optical means is installed in the vicinity of a ridge portion thereof that is the least susceptible to deformation and distortion and strongest in its strength. Thus, it becomes possible to improve a light image in its precision that is formed by the scanning beam directed onto the image-bearing body.

In a space portion where all light-scanning units are housed, an air-exhausting fan is provided in the vicinity of the light-scanning unit nearest to the thermally fixing unit, and an air hole is formed at a position farthest from the thermally fixing unit. Additionally a temperature sensor is mounted on the light-scanning unit nearest to the thermally fixing unit. Rotation speed of the air-exhausting fan is controlled so that the temperature detected by the sensor does not exceed a predetermined temperature limit.

摘要： An image-forming unit 100 in a complex device A forms a correction-use image onto a sheet in accordance with data, in such a manner that the correction-use image thus formed partly on and partly off the sheet and includes edges of the sheet, the date being preliminarily determined in accordance with a size of the sheet. An image-detecting section 520 reads that portion of the correction-use image which is transferred on an image-transfer belt 7 as the correction-use image is formed by the image-forming unit 100. A correction value is calculated in accordance with data thus obtained by the image-detecting section 520. A control section then causes a data storing section to store the correction value. The control section reads out the correction value when forming an image in the complex device A, and forms the image, performing correction of the image, using the correction value for correcting an image-forming condition regarding how the image is formed on the sheet. The image-forming condition, such as a position and a copy-scale, can be adjusted, even if using an unadjusted reading apparatus.

摘要： An adjustment method for an image forming device, for adjusting image forming condition with respect to a sheet by using image forming means. The adjustment operation is performed in such a manner that: a first image, that is used for detecting scanning error of an image scanning device, is formed on an image carrying body and then transferred from the image carrying body to the sheet, the first image being formed over at least three corners of the sheet while extending outside the sheet. The sheet with the first image is scanned by the image scanning device to figure out a scanning error amount of the image scanning device, and a correction value of image forming condition of the image forming means is found in consideration of the scanning error amount. The image forming condition with respect to the sheet is modified based on the correction value.

摘要： An image forming device and a color misregistration correction method allow for stable formation of excellent images with little color misregistration. A reference patch image is formed on a reference photosensitive drum 3, and transferred to a transfer belt 7. A correction patch image is formed on a correction-target photosensitive drum 3, and transferred onto the reference patch image by superimposition. A registration detecting sensor 21 detects a density average value of the reference patch image and the correction patch image. Based on the density average value, a correction value for controlling the correction-target photosensitive drum 3 is calculated, and rotational phase control is performed in accordance with the correction value.
