Abstract
Provided is an image forming apparatus capable of reducing a downtime for switching between a monochrome image forming mode and a color image forming mode. In the image forming apparatus, images formed by a plurality of image forming stations are transferred in superimposition onto a transfer member. Further, the image forming apparatus controls image formation in each of a first mode of performing image formation using only an image forming station located at the most downstream position in a moving direction of the transfer member among the plurality of image forming stations, and a second mode of performing image formation using the plurality of image forming stations.
