Abstract
PURPOSE:To eliminate a need of destaticizers by controlling an electrostatic latent image forming means, which exposes the overall surface of a photosensitive body by the laser beam light to form an electrostatic latent image, in the photosensitive body destaticizing process after image formation. CONSTITUTION:The electrification control type means which negatively electrifies a photosensitive body 11 is used as an electrifying means 12. After the photosensitive body 11 is electrified, only the information area on the photosensitive body 11 becomes 0V by reversal exposure by means of scanning of a laser beam light B of an electrostatic latent image forming means 13, and then, an electrostatic latent image is formed. This image is developed by reversal development with toner negatively electrified by a developing means. The image is transferred onto a form P by a transfer means 15 having a polarity opposite to that of toner. The transfer means 15 having the positive polarity is turned off after image formation, and the electrification control type means 12 is turned off after the positive electric charge remaining between the transfer means 15 and the means 12 on the photosensitive body 11 is uniformly negatively electrified by the means 12. The laser beam light B from the electrostatic latent image forming means 13 is controlled by a control means 16 to remove the electrostatic charge on the photosensitive body 11 by overall exposure, and thereafter, rotation of the photosensitive body 11 is stopped. By this constitution, destaticizers are made unnecessary to miniaturize a device.
