摘要： An average concentration value is detected within a measurement area (about 10 dots) corresponding to the pitch of a detection pattern in the total color matching adjustment range (100 dots), and from a value detected as a local maximum value, a candidate for correction value for the exposure timing of an adjustment image is acquired within the color matching adjustment range. This process is carried out for two types of detection patterns having different pitches thereby to acquire two candidates. A correction value for the exposure timing is determined from a candidate shared by the two detection patterns. At the time of color matching adjustment, the wasteful consumption of the developer or the like is suppressed, while carrying out the color matching adjustment efficiently within a short time.

摘要： An object of the invention is to reproduce a faithful image irrespective of thermal expansion of a light-scanning unit and to reproduce a faithful image without enhancing the strength of the light-scanning unit excessively. A pair of supporting portions of a light-scanning unit, each having a flat face, are supported in linear contact with a right column-shaped supporting member provided with the apparatus body. The light-scanning unit is provided on the supporting member near to a starting position where writing image data on a photosensitive body with a scanning line is started in a main scanning direction so as not to be mutually displaced relative to the supporting member. Thereby, the light-scanning unit is allowed to extend in the longitudinal direction of the supporting member due to thermal expansion of the light-scanning unit. Also, an elongated supporting member made of stainless steel penetrates a base body of a light-scanning unit made of synthetic resin which scans in scanning line of laser light on the photosensitive body to exposure, to support the light-scanning unit. The center of gravity of the light-scanning unit is positioned near to the supporting member and vertically below the supporting member, to make the moment acting on the light-scanning unit small and hold the light-scanning unit in a stable state. The supporting member suppresses deformation of the base body due to thermal expansion.
摘要翻译：本发明的目的在于，不管光扫描单元的热膨胀如何，再现忠实的图像，并且在不增加光扫描单元的强度的情况下再现忠实的图像。具有平面的光扫描单元的一对支撑部分与设置有装置主体的右柱状支撑构件线性接触地支撑。光扫描单元设置在靠近起始位置的支撑构件上，其中在扫描线上的感光体上的图像数据在主扫描方向上开始，以便不相对于支撑构件相互位移。由此，由于光扫描单元的热膨胀，允许光扫描单元在支撑构件的纵向方向上延伸。此外，由不锈钢制造的细长支撑构件穿透由合成树脂制成的光扫描单元的基体，其在感光体上的扫描激光线上扫描以曝光，以支撑光扫描单元。光扫描单元的重心位于支撑构件附近并且垂直于支撑构件的下方，以使作用在光扫描单元上的力矩较小并将光扫描单元保持在稳定状态。支撑构件抑制由于热膨胀而引起的基体的变形。

摘要： A plurality of first base images for a base color are formed in accordance with a predetermined adjustment value. A plurality of first correction images for a correction color to be a subject for correction are formed on the first base images 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 for the base color are formed in accordance with the predetermined adjustment value while the second correction images for the correction color are formed in accordance with a plurality of adjustment values determined based on the first adjustment value. One second adjustment value having an extreme is determined from the plurality of adjustment value candidates. These processes are repeated to determine a final adjustment value. The adjustment value for the correction color is corrected to the determined final 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.
