摘要： The invention concerns an improvement of a drive system of a color image forming apparatus. The color image-forming apparatus includes a plurality of image-forming elements; a plurality of first driving motors, each of which corresponds to each of the image-forming elements, to drive the plurality of image-forming elements; an intermediate transfer element that is disposed opposite the plurality of image-forming elements; a second driving motor to drive the intermediate transfer element; and a controlling section to control the plurality of first driving motors and the second driving motor. In the color image-forming apparatus, the controlling section controls the plurality of first driving motors and the second driving motor independently of each other, so that a first peripheral speed of each of the image-forming elements coincides with a second peripheral speed of the intermediate transfer element.

摘要： When conducting a color-shift-correcting mode using a registration mark formed by the image forming means on an image carrier, the image detecting means outputs the image detection signal representing the line width of the registration mark and the control section calculates the line width of the registration from the image detection signal. The control means compares a line width of the registration mark with a predetermined reference value of the line width to discriminate between abnormality and normality. If normality, the control means continues the color-shift-correcting mode and if abnormality the control means conducts the image forming system restoration mode after stopping the execution of the color-shift-correcting mode. Therefore, even in the case where a white spot is generated for some reasons on the registration mark, the color-shift-correcting mode can be conducted on the normal registration mark with the help of the image forming system restoration mode.
