PURPOSE:To reduce the loss of time caused by a protocol between a main control means and a sequence control means by allowing the sequence control means to stepwise and continuously execute different image forming actions with continuous timing with signals for executing the different image forming actions by several times from the main control means. CONSTITUTION:The sequence control part stepwise and continuously executes the different image forming actions with the continuous timing by commands to start corresponding to jobs 1-4 transmitted from the main control part respectively. As the commands to start, a printing start signal (1) for the job 1, a printing start signal (2) for the job 2, a paper election count signal (3) for the job 1, a printing start signal (4) for the job 3, a paper election count signal (5) for the job 2, a printing start signal (6) for the job 4, a paper ejection count signal (7) for the job 3, a paper election count signal (8) for the job 4 and a printing stop signal (9) are obtained. |
