This invention has as its object to improve an image formation throughput. An image forming apparatus of this invention times a time required until an image formation is ready to start after a reference signal is output, and executes the image formation when the image formation is ready to start (for example, initial processes are complete). Furthermore, when the next reference signal is output during the image formation, the image forming apparatus executes an image formation of the next color after a waiting process based on the timed time. |
