Abstract
A controller of an image forming apparatus determines whether switching of a monochromatic recording mode to a color recording mode is necessary or not. In the case where the controller determines that the switching is necessary, the controller controls stepping motors of respective image forming units corresponding to respective colors of yellow, cyan, magenta and black to lower their outputs. Then, the controller controls a power transmission mechanism to execute a connecting operation so as to transmit a driving force to each of the image forming units corresponding to yellow, cyan and magenta. At the timing when the color printing should be performed, the controller controls respective developing rollers to start performing a developing operation in order of yellow, cyan, magenta and black.
