ABSTRACT:
An image forming apparatus having plural image carriers, respective chargers, exposure units, color toner developing units, a black toner developing unit, a transfer unit that transfers in the transfer section the color toner images and black toner image onto an intermediate transfer member by the application of a transfer bias from the power supply unit, and a controller that controls the transfer output, an an optical density sensor that detects the optical density of color toner patch images formed on the intermediate transfer member, and a controller transfers the color toner patch images onto the intermediate transfer member while changing the transfer output, detects the optical densities of color toner patch images transferred onto the intermediate transfer member using the optical density sensor, and controls the transfer output to transfer the black toner image based on the detected optical densities of the color toner patch images.
