Color shift correcting structure of image forming apparatus |
摘要 |
An image-forming device such as a full color printer is provided which is designed to correct the speed of an image carrier such as a sheet conveyer belt for compensating for a shift between colors. The image-forming device forms electrostatic marks on the image carrier at regular intervals and detects the marks using a sensor(s) to determine a change in speed of the image carrier based on sensor signals.
