Abstract

PURPOSE:To prevent a greater part of input and output ports from being used for key input displaying or sequence controlling of various image formation by making control means having programs for potential controlling independent from control means having programs for sequence controlling. CONSTITUTION:A CPU1 is a microcomputer stored with programs for outputting the signals for driving and controlling various parts of a copying apparatus, and outputs a drum rotation signal DRMD, original platen advance signal SCFW, retreat signal SCRV, etc. based in the input signals such as the drum clock pulses DCK synchronized to the rotation of a drum 47, jam detection signal JAM and the signal from a key matrix KM. The various signals of the computer CPU1 for sequence controlling are inputted via buffers Q20, Q21, to a computer CPU2 for potential controlling. The CPU4 takes surface potential A/D conversion data therein and makes predetermined arithmetic operations. With such constitution, the development of programs such as charger controlling, developing bias controlling or the like is made possible independently from the sequence control programs.
