摘要： A plurality of first base images are formed from a base color output in accordance with a predetermined adjustment value. A plurality of first correction images are formed on the first base images from a correction color to be a subject for correction output in accordance with a predetermined adjustment value. The first correction images are displaced within a predetermined range. The first adjustment value is determined from changed adjustment values. The second base images are formed from the base color output in accordance with the predetermined adjustment value, and the second correction images are formed from the correction color output in accordance with a plurality of adjustment values determined based on the first adjustment value. The second adjustment value having an extreme is determined from a plurality of adjustment value candidates. Finally, the adjustment value for the correction color is corrected to the determined second adjustment value.

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： An object of the invention is to provide an image forming apparatus in which a unit can be attached to the apparatus body in a status where a correct positional correlation between a photoconductive drum and each of other process devices mounted on a unit is maintained. A photoconductive drum is positioned within a copier body by a rotating drive shaft, and the other process devices mounted on a process unit are positioned within a copier body by a boss and a locking member. The boss positions the rotating drive shaft within the copier body. Since the locking member is fitted onto a front-side end of the rotation drive shaft, the locking member is positioned within the copier body by the rotating drive shaft. The other process devices mounted on the process unit are positioned within the copier body by the rotating drive shaft via the boss and the locking member. Accordingly, the photoconductive drum and each of the other process devices, which should maintain a predetermined positional correlation with each other within the copier body, are both positioned within the copier body by the rotating drive shaft.

摘要： When an instruction to execute a color registration adjustment process is given (S1), an image forming apparatus deactivates a sheet feed driving section and a fixing unit (S2), stops communications with external devices (S3), invalidates control sensors excluding an operation section, a door sensor, and sensors involved in formation of images for adjustment (S4), stops a fan (S5), and then executes the color registration adjustment process by forming reference lines and correction lines on a transfer belt and detecting misregistration between them (S6). With this image adjustment method, it is possible to reduce wasteful consumption of developer and efficiently execute the color registration adjustment in a short period of time.

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： Assuming the photosensitive drum for black as a reference, the phase of the adjacent photosensitive drum for cyan leads by about 60 deg. Similarly, the phase of the photosensitive drum for magenta leads by about 120 deg., and the phase of the photosensitive drum for yellow leads by about 180 deg. The phase of each photosensitive drum is shifted to thereby make it possible to shift the phase of driving unevenness. By shifting the phase, even the distance between adjoining transfer positions corresponding to the image forming stations is set shorter than the circumference of the photosensitive drum, the variation of each photosensitive drum due to driving unevenness with respect to the printing medium passing through the transfer position can be kept congruent with the others.
