Abstract

PURPOSE:To reduce the size of an image forming device and to improve the quality of an image by passing image exposure light from a 2nd laser exposure means through an electrostatic recharging device, and performing electrostatic charging and image exposure at the same time. CONSTITUTION:An intermediate electrostatic charging device 5 is formed between the bottom plate 4a of a 1st developing device 4 and the top plate 7a of a 2nd developing device and an electrostatic charging device house is consisted of a flank shield plate and a rear shield plate 5a. Further, a slit 5b is formed on the rear shield plate 5a and 2nd laser image exposure light is projected through the slit 5a to perform image exposure for a 2nd color by a 2nd laser image exposure means 6 while performing electrostatic recharging at a 1st color exposed part which is already developed by an intermediate electrostatic charger 5. This constitution performs image exposure in the electrostatic charger 5 to increase contrast and a 2nd developing device 7 is close to the side of the electrostatic charger 5 to output high picture quality.
