摘要： An image forming apparatus forms a color image by superimposing images formed in a plurality of colors. To prevent color deviations from occurring in the image forming apparatus, a predetermined registration pattern is formed in each of the plurality of colors, and an image forming position is adjusted for each color in accordance with a detection result given by a detecting unit on detecting the predetermined registration pattern. A value of a parameter having an effect on an output of the detecting unit is set for each color so that the value set for at least one of the colors is different to the values respectively set for other colors. The value of the predetermined parameter may be set as a fixed value for each color. Alternatively, the value of the predetermined parameter may be a variable that is automatically set.

摘要： In order to provide a driving mechanism for a photosensitive drum which is capable of reducing deformation of the shaft of the photosensitive drum caused by loads when transmitting a driving force, a drive transmission course 51 is diverged to at least two courses in a drive transmission system 42 for transmitting the drive force from a drive motor 41 to the photosensitive drum 25. Specifically, the last stage of the drive transmission course 51 is engaged with a passive member 47 provided to the drum shaft 25a at two or more points to connect and link the drive force, thereby diverging the directions of loads to several directions, by which irregular movements of the photosensitive drum or vibration caused by the deformation of the shaft is eliminated.
