The present invention relates to an image forming apparatus having a plurality of developing units, one of which is selectively used for development. The image forming apparatus of the present invention provides for removing the toner intruding into the other developing unit. As a result, the intruding developer on the outer periphery of its developing sleeve can be removed from the developing station before a selected developing unit is initiated into developing operation.
