Abstract

PURPOSE:To enable the output of a primary electric charger charging on a recording body to be controlled by providing a microcomputer for sequence controlling and a microcomputer for potential controlling. CONSTITUTION:This apparatus has a primary charger 51 which forms electrostatic latent images on a recording body such as photosensitive drum 47, a developing device 62 which develops the latent images, a surface electrometer 67 which measures the surface potential on the drum 47, a microcomputer which has been stored with the programs for sequence controlling the primary charger 51, and a potential control computer which has been stored with the programs for controlling the latent image forming conditions of the primary charger 51 or the developing conditions of the developing device 62 by the output of the surface electrometer 67. The latter computer is controlled by the timing signal from the former computer. With such constitution, programming is made possible simply by preparing a very small number of timing signals for the control programs that perform sequence controlling.
