Abstract
An image forming apparatus capable of operating in a full-color mode or in a monochrome mode includes a first driving mechanism, a second driving mechanism, a transfer member, and a controller. The first driving mechanism drives the color image carriers and the second driving mechanism drives a black image carrier in a first direction to form a color and black toner images on a transfer member. The controller synchronizes the first driving mechanism and the second driving mechanism after conducting an image forming operation in the full-color mode or in the monochrome mode to conduct a phase alignment between the color image carriers and the black image carrier.
